Knitting electronics with yarn batteries

When someone thinks about knitting, they usually don't conjure up an image of sweaters and scarves made of yarn that can power watches and lights. But that's just what one group is reporting. They have developed a rechargeable yarn battery that is waterproof and flexible. It also can be cut into pieces and still work.

The future of photonics using quantum dots

Fiber-optic cables package everything from financial data to cat videos into light, but when the signal arrives at your local data center, it runs into a silicon bottleneck. Instead of light, computers run on electrons moving through silicon-based chips, which are less efficient than photonics. To break through, scientists have been developing lasers that work on silicon. Researchers now write that the future of silicon-based lasers may be in quantum dots.

How to Connect ESP8266 to WiFi | A Beginner’s Guide

In the previous ESP8266 Projects, I have given a brief introduction to ESP8266 WiFi Module, how to get started with ESP8266 and Arduino, what is the pin configuration of the ESP8266 ESP-01 Module and how to program the ESP8266 using Arduino as USB-to-Serial Interface.

I have also shown you how to install firmware (AT Commands Firmware) onto the on-board ROM of the ESP8266 WiFi Module.

One thing (and it is an important thing) that I have missed (not intentionally) is to show you How to connect ESP8266 to WiFi Network.

So, without further ado, let me show you how to connect ESP8266 to WiFi and use it in our IoT (Internet of Things) and other WiFi based Projects.

NOTE:

• Before proceeding, I strongly recommend you to refer to two of the earlier projects on ESP8266 WiFi Module: GETTING STARTED WITH ESP8266 AND ARDUINO and HOW TO UPDATE/FLASH ESP8266 FIRMWARE.
• There are many important things like Pin Configuration of ESP8266 (ESP-01) Module, How to connect ESP8266 to Arduino, and so forth that you must have a prior knowledge on before proceeding to connect ESP8266 to WiFi.  

Overview

The tiny ESP8266 (ESP-01) WiFi Module is making wonders in the DIY Community as it allows devices like Arduino to access Web Pages by connecting to the Internet.

The ESP8266 WiFi Module can be interfaced to any other microcontroller (like Arduino or 8051) through UART and with the help of AT Commands, the Microcontroller can control the ESP8266 (connect to WiFi, update Firmware, etc.).

So, in order to use the ESP8266 WiFi Module in our Internet related projects, we need to first connect ESP8266 to WiFi and then access it from the internet.

Before going into the details of how to connect ESP8266 to WiFi, you need to understand the WiFi modes of operation of the ESP8266 Module.

WiFi Modes of Operation of ESP8266

There are three modes of WiFi Operation in the ESP8266 WiFi Module. They are:

• Station Mode (STA)
• Soft Access Point (AP)
• Soft AP + Station

Station Mode (STA)

In Station Mode (STA), the ESP8266 WiFi Module will be connected to a WiFi Network that is already setup by an Access Point, like a WiFi Router.

Soft Access Point (AP)

The second mode of operation is Access Point (AP) Mode. In this mode, the ESP8266 Module acts as an access point and provide WiFi Network to other stations (like mobile or laptop).

Usually, an access point can provide internet through a wired network to its stations but as there is no wired interface, this Access Point mode is called Soft Access Point.

The ESP Module is first setup as Soft AP mode before configuring it in Station Mode. This is helpful when the username (SSID) and password of the WiFi network is unknown.

Soft AP + Station

In the third mode, the ESP8266 WiFi Module is configured to act in both Station Mode and Soft AP Mode.

All these Modes of Operation are set using AT Commands. In this tutorial, I will discuss about the AT Commands that are required to connect ESP8266 to WiFi Network. In a separate tutorial, I’ll talk about some of the important and useful ESP8266 AT Commands.

Circuit Diagram

Components Required

• ESP8266 (ESP-01) WiFi Module
• Arduino UNO (an USB-to-Serial Adapter is sufficient)
• Push Button
• Slide Switch
• 1 KΩ Resistor (1/4 Watt)
• 2.2 KΩ Resistor (1/4 Watt)
• Connecting wires

How to Connect ESP8266 to WiFi Network using AT Commands?

Before seeing how to connect ESP8266 to WiFi network, you have to remember that the ESP8266 WiFi Module is loaded with AT Commands Firmware.

Please refer to the project “HOW TO FLASH FIRMWARE ON ESP8266” before proceeding with connecting the ESP8266 WiFi Module to a WiFi Network.

So, after connecting the ESP8266 in Programming Mode and ensuring that it has AT Commands Firmware, connect the Arduino to the Computer and open the Serial Monitor.

In my case, I have set the Baud rate to 115200 and also selected “Both NL & CR” option in the Arduino’s Serial Monitor. Change these settings as per your requirements.

First, type the following command to test whether the communication is successful or not.

AT

Then, I will restart the ESP8266 Module using the following command, just to make sure that I start fresh.

AT+RST

Now, I need to set the Mode of operation as Station Mode. For this, use the following command.

AT+CWMODE=1

The Mode of Operation has been set as Station Mode (STA). Now, to see the list of all the nearby WiFi Networks, use the command shown below.

AT+CWLAP

In order to join a network, use the following command.

AT+CWJAP=”SSID”,”PASSWORD”

In place of SSID, type the name of your WiFi Network and in place of PASSWORD, well type the password.

Within few seconds, you will get a confirmation response as WIFI Connected. In order to check the IP Address of the ESP8266 WiFi Module, type the command.

AT+CIFSR

Alternative Way to Connect Your ESP8266 WiFi Module to a WiFi Network

If you are tired of typing all these AT Commands in order to connect ESP8266 WiFi Module to a WIFi Network, then there is an alternative way. In this method, I’ll be programming the ESP8266 WiFi Module (which means the AT Command Firmware will be erased). The code for this is shown below.

NOTE: In the code, enter the details of your WiFi Network in place of “ssid” and “password”.

Before programming, select the “Generic ESP8266 Module” from boards and also select the correct COM Port. More information about programming ESP8266 WiFi Module (Blink example) can be found here: GETTING STARTED WITH ESP8266 AND ARDUINO.

Now, connect the GPIO0 to GND and reset the ESP and hit the upload button. The ESP8266 WiFi Module will be automatically connected to the specified WiFi Network and it also responds with the IP Address.

Conclusion

In this project/tutorial, I have shown you how to connect an ESP8266 WiFi Module to a WiFi Network using both AT Commands and programming. In the next tutorial, I’ll highlight some of the important AT Commands of the ESP8266 Module.

How to Control ESP8266 over Internet?

In the previous project, I have shown you a simple setup for WIFI CONTROLLED LED USING ESP8266 AND ARDUINO. In this project, I will show you How to Control ESP8266 over Internet i.e. controlling ESP8266 from anywhere in the World through Internet.

Overview

Even though the main purpose of ESP8266 WiFi Module is to introduce Internet Connectivity into our small DIY Projects, I believe that we haven’t completely utilized the capabilities of the ESP8266 WiFi Module until now i.e. a true IoT (Internet of Things) Project.

I want to take the ESP8266 Projects a step further by actually controlling the ESP8266 over the Internet. In this process, we will learn how to control ESP8266 over Internet by controlling an LED (just to demonstrate the working) connected to one of the GPIO Pins of the ESP8266 WiFi Module over the internet i.e. another network to with the ESP8266 isn’t connected to.

How is this different from the WiFi Controlled LED Project?

Very good question. There are actually two differences between this project and the earlier project. The first difference is how the ESP8266 WiFi Module is controlled. In the previous project, I controlled the ESP8266 through WiFi network i.e. from a computer or phone that is connected to the same network as the ESP8266.

Coming to this project, the aim is to control the ESP8266 over the internet i.e. from a computer or phone anywhere in the World with an internet connectivity.

The second difference is how the ESP8266 WiFi Module is configured. If you remember, I have mentioned particularly that ESP8266 WiFi Module must be flashed with AT Commands Firmware and we will be controlling the ESP8266 through the Program uploaded to Arduino.

But, in this project, I will be directly uploading the code into the ROM of the ESP8266 WiFi Module (the existing program or firmware will be erased).

Now that we have seen the differences, let us proceed with the circuit diagram and the circuit design of the project.

Circuit Diagram

The following circuit is used to control ESP8266 over internet. Let us take a look at the components first and then I will explain the design of the circuit in detail.

The following image shows the pins of the ESP8266 WiFi Module used in the circuit diagram. For actual pin diagram, please refer to the GETTING STARTED WITH ESP8266 AND ARDUINO Project.

Components Required

• Arduino UNO (as USB to Serial Converter)
• ESP8266 (ESP-01) WiFi Module
• Slide Switch (SPDT Switch)
• Push Button
• 1 KΩ Resistor (1/4 Watt)
• 2.2 KΩ Resistor (1/4 Watt)
• 330 Ω Resistor (1/4 Watt)
• LED
• Connecting Wires
• Mini Breadboard

NOTE:

• Arduino UNO is used as an USB to Serial Converter. So, I have removed the ATmega328p Microcontroller from the Arduino UNO Board. If you have a dedicated USB to Serial Converter (USB-to-TTL), then you won’t need Arduino.
• Also, I have made a simple ESP8266 Breakout Board in an earlier Project called DIY PCB FOR ESP8266. It contain all the important components associated with the ESP8266 WiFi Module. I will be using the same board in this project.

Circuit Design

Connect the VCC and GND of the ESP8266 to 3.3V and GND of the Arduino. The CH_PD pin is also connected to the 3.3V Supply. A Push Button is connected between the Reset Pin and GND.

The TX Pin of the ESP8266 WiFi Module is connected to the TX pin of Arduino and the RX Pin of the ESP8266 is connected to the RX Pin of the Arduino but through a voltage divider consisting of two resistors (1 KΩ and 2.2 KΩ).

An LED is connected to the GPIO2 pin of the ESP8266. Finally, the GPIO0 pin is connected to the Pole of a SPDT Switch (center terminal of the slide switch). One throw terminal of the switch is connected to GND and the other throw terminal is left open but can be used for GPIO connection.

Code

The following program must be uploaded to the ESP8266 WiFi Module. It will setup the WiFi Connection and also creates a simple HTML Page that can be accessed using the IP Address of the ESP8266.

NOTE:

• Before uploading the code to ESP8266, make sure that “Generic ESP8266 Module” is selected in the Arduino Boards section.
• For more information on how to upload a program to ESP8266, refer to the Getting Started with ESP8266 and Arduino Project.
• Enter the details of your WiFi network in the Code.
• I have assigned a Static IP Address for ESP8266 WiFi Module in the code as “192.168.1.254”. I have chosen this address after confirming that there is no other device with this IP Address. You make sure of the same when assigning static IP address.
• Along with the Static IP Address, you must also provide additional information like Default Gateway and Subnet Mask. You can find this by typing “ipconfig” in the command prompt of the Windows.

Working

In order to upload the code, slide the GPIO0 pin to programming mode (connect GPIO0 to GND) and press the RESET Switch. After selecting the correct board and port in the Arduino IDE, upload the code.

Once the code is uploaded, slide the switch to normal mode and push the RESET button once. Open the serial monitor. There you can see the details of the WiFi Connection.

You can also see the IP Address of the ESP8266 WiFi Module. Since I assigned a Static IP Address, I will get the same. If you have chosen not to assign a static IP Address, then use the address assigned by your router.

In the code, I have created the Server at Port 255. So, the URL of the server will be http://ift.tt/2GQHS6N.

Open a web browser in a computer or phone connected to the same WiFi Network and enter the above mentioned URL. A simple HTML page will be opened with few texts and links. The following image is a screenshot of a phone which has opened the URL.

You can click on the specific links to control the LED locally i.e. within the WiFi Network.

How to Control ESP8266 Over Internet?

Now the trick part of controlling the ESP8266 WiFi Module over the Internet. There are two way you can achieve this. One way is to use Port Forwarding, which I will be using in this project and the other way is to use dedicated remote servers like ThingSpeak or aREST.

As I have already set a Static IP Address to my ESP8266 WiFi Module, the next step is to proceed with port forwarding.

Open your router page from any browser and login using router login details. Go to Port Forwarding page of your router (depends on router, in my case it was I WAN Settings).

Enable Port Forwarding and provide necessary details like Local Server IP Address (static IP Address of ESP8266), Port Number, etc. and save the settings.

Now, go to the Windows Firewall with Advanced Security Settings and add a new inbound rule. Select the rule type for “Port” and specify the port number.

Open any web browser and search for “what is my ip address”. It results in the WAN IP Address of your Router. Note it down.

Now, from another computer (any computer that is not connected to the same WiFi Network as the ESP8266), type the IP Address you just noted down along with the Port number. For example, if your IP Address is 183.92.192.58 and the port number is 255, then type “183.92.192.58:255” in any web browser. You will now get the HTML page to control the LED.

IMPORTANT NOTE:

• Port Forwarding is not recommended as it opens up the computer to outside world and can be easily attacked by virus or malware.
• Also, many ISPs (Internet Service Providers) do not allow port forwarding.
• An alternative is to use the dedicated secure servers like ThingSpeak or aREST.
• In the next project, I’ll show you how to control ESP8266 from the internet using one of those services.

Next-gen X-ray microscopy platform now operational

COSMIC, a next-generation X-ray beamline now operating at Berkeley Lab, brings together a unique set of capabilities to measure the properties of materials at the nanoscale. It allows scientists to probe working batteries and other active chemical reactions, and to reveal new details about magnetism and correlated electronic materials.

Make way for the mini flying machines

Tiny floating robots could be useful in all kinds of ways, for example, to probe the human gut for disease or to search the environment for pollutants. In a step toward such devices, researchers describe a new marriage of materials, combining ultrathin 2-D electronics with miniature particles to create microscopic machines.

Improving fabrication process of nano-structures for electronic devices

Researchers have found a more efficient fabricating process to produce semiconductors used in today's electronic devices. They also confirmed that materials other than silicon can be used successfully in the development process that could increase performance of electronic devices.

'Candy cane' polymer weave could power future functional fabrics and devices

If scientists are going to deliver on the promise of implantable artificial organs or clothing that dries itself, they'll first need to solve the problem of inflexible batteries that run out of juice too quickly. Today, researchers report that they've developed a new material by weaving two polymers together in a way that increases charge storage capacity.

Don’t get stuck in the cheese

Hans is a 35-year-old guy who loves to learn about how things work. He has no previous experience with electronics, but now he wants to learn.

He learns about the transistor, the resistor, and the capacitor. And he feels he understands them, at least at a basic level.

But when he thinks about his dream project – an RFID-activated door for his cat – he has no idea how to do it. He figures he has to understand these components even better before he can move on.

So he keeps reading about them.

But still, he can’t seem to see the connection from these simple devices to his dream project.

“There must be something I’m missing,” he thinks to himself.

And he refuses to move on to the next topic until he fully understands the connection.

This is a very typical situation.

But here’s the problem:

You won’t learn to make pizza simply by understanding cheese really well!

If you want to learn to make pizza, you need to study how to make pizza! You need to learn what the basic ingredients are, and how you combine them into a pizza.

If you find cheese really interesting, by all means, study cheese. But don’t forget to study pizza if that’s your goal.

Tomorrow, I will launch my newest online training: Practical Electronics For Beginners (PEFB)

A workshop with a beep

“Beeeeep!”

That’s the sound we were surrounded by all night.

About a month ago, I did a workshop in Oslo together with two very skilled electronics enthusiasts.

I thought it was a good idea to program all the chips with a beeper-example program.

So when people had soldered their circuit, they would know if it worked.

Oh yes, the beeper worked!

It was beeping all night for two hours straight.

Next time, I’ll choose something less noisy.

But since then, I’ve been itching to do another online class.

I’ve been working hard for several weeks now, but it is finally coming together. And I have decided to open the enrollment on Wednesday.

There will be beeps.

There will be blinks.

And there will be a lot more.

I’ll be more specific next week.

Until then…

WiFi Controlled LED using ESP8266 and Arduino

In this ESP8266 WiFi Module Project, we will learn about WiFi Controlled LED using ESP8266 and Arduino. I will show you how to control an LED connected to the Digital I/O Pin of the Arduino over WiFi Network using the ESP8266 WiFi Module.

Overview

The ESP8266 WiFi Module is an interesting addition to the makers and hobbyists’ community as it allows us to integrate WiFi and Internet into our DIY Projects.

IoT or Internet of Things is one such area which can be implemented using a variety of sensors connected to a Microcontroller like Arduino and ESP8266 WiFi Module to access the sensor data from anywhere in the World.

Before thinking about big IoT projects, let us begin exploring the ESP8266 WiFi Module and implement a small but useful project called WiFi Controlled LED using ESP8266 and Arduino. 

I have already introduced to you about the ESP8266 WiFi Module in my GETTING STARTED WITH ESP8266 AND ARDUINO Project. Refer to that project first in order to learn about the basic information on ESP8266 WiFi Module, its Pin Diagram, pin configuration and how to interface ESP8266 with Arduino.

IMPORTANT NOTE:

• In my second project on ESP8266 WiFi Module, I have shown you How to flash the AT Command Firmware onto the ROM of ESP8266 WiFi Module.
• It is very important that you first implement that project i.e. make sure that your ESP8266 WiFi Module has AT firmware installed on it.
• If you have programmed your ESP8266 WiFi Module with other program (like Blink, for example), then you must flash the firmware. If your ESP module is already has the AT Commands firmware, then leave it as it is.

Concept behind WiFi Controlled LED using ESP8266 and Arduino

Before getting into the details of the project like the circuit diagram, components, connections and the code, let me take you through the concept behind the WiFi Controlled LED using ESP8266 and Arduino.

The idea behind the project is very simple. Connect an LED to the Arduino Board. This LED must be connected over WiFi i.e. within a local network through a Smart Phone or a Laptop.

For this, use the ESP8266 WiFi Module and interface it to Arduino through Serial Communication. Arduino will command the ESP8266 module to get connected to a WiFi network and receive data from the client (an HTML page).

Based on the information sent by the client (with the help of a Web Browser), the Arduino will either turn ON or OFF the LED. That’s it.

Circuit Diagram

The circuit diagram for the WiFi Controlled LED using ESP8266 and Arduino project is shown I in the image below.

Components Required

• Arduino UNO
• ESP8266 WiFi Module
• LED
• 330Ω Resistor (1/4 Watt)
• 1 KΩ Resistor (1/4 Watt)
• 2.2 KΩ Resistor (1/4 Watt)
• Push Button
• Connecting Wires
• Mini Breadboard

Circuit Design

I have used the software serial feature of the Arduino and made its digital pins 2 and 3 as RX and TX. These pins must be connected to TX and RX Pins of the ESP8266 WiFi Module.

NOTE: I have used a level convertor consisting of a 1 KΩ Resistor and a 2.2 KΩ Resistor before connecting the TX Pin of Arduino (Pin 3) to the RX Pin of the ESP8266.

An LED is connected to the Digital I/O Pin 11 of the Arduino. (This is the LED that we will be controlling over WiFi).

Coming to the rest of the connections with respect to the ESP8266, it’s VCC and CH_PD pins are connected to 3.3V of the Arduino and GND is connected to, well the GND pin of the Arduino. A Push Button is connected between RESET of ESP8266 and GND.

Both the GPIO Pins of the ESP8266 i.e. GPIO0 and GPIO2 are left open as we won’t be using those pins in this project.

Code

The following is the code that is to be uploaded into Arduino. It will configure the WiFi in the ESP8266 Module as well as check for the data from the HTML page (will be discussed later).

HTML Code for Sending Data to ESP8266

In order to create an interface for the project, I have created a simple HTML based webpage. The HTML code for this webpage is given below.

Download this HTML Code (save it as .html file).

This HTML webpage uses the JavaScript library “jQuery.js”. Download this library from here and place it in the same folder as the .html file.

So, your webpage folder consists of two file: one “webpage.html” file and a “jQuery.js” file. Open the HTML file using any web browser. The interface looks like this.

Working of WiFi Controlled LED using ESP8266 and Arduino Project

Upload the Arduino Code provided above to your Arduino Board after making all the necessary connections. Once the code is uploaded, open the Serial Monitor of Arduino. You can see the progress of the setup done on the ESP8266 WiFi Module.

Some of the information in the above image looks garbage but I assure that correct data is transmitted. If you got a clean response, you can find the IP Address of the ESP8266 Module at the highlighted place in the image above.

Since I couldn’t find the IP Address from Serial Monitor, I had to look up for it using another tool called “Advanced IP Scanner”.

Now, open the webpage that you saved earlier and enter this IP Address in the IP Address field provided. After entering the IP Address, you can click on the Button on the page to turn ON and OFF the LED.

Conclusion

A simple project called WiFi Controlled LED using ESP8266 and Arduino is designed here where an LED connected to Arduino is controlled over WiFi (within the same network).

Any device connected in same WiFi Network can control the LED with the help of a simple HTML webpage.

The next step or an advanced version of this project will be controlling the LED over internet i.e. from anywhere in the World (involves PORT Forwarding).

Graphene flakes for future transistors

Tiny and very promising for possible applications in the field of nanoelectronics: they are the graphene nanoflakes. These hexagonal shaped nanostructures would allow to exploit quantum effects to modulate the current flow. Thanks to their intrinsic magnetic properties, they could also represent a significant step forward in the field of spintronics, which is based on the electron spin.

Existence of new form of electronic matter

Researchers have produced a 'human scale' demonstration of a new phase of matter called quadrupole topological insulators that was recently predicted using theoretical physics. These are the first experimental findings to validate this theory.

Mixed-plastic electronics waste could be a valuable source of reusable polymers, a new study suggests. The team has developed the first energy-efficient and environmentally friendly process that separates mixed polymers so that they can be recycled into new, high-quality plastic products.

DIY PCB for ESP8266 WiFi Module

Overview

In this project/tutorial, I’ll show you how to design and develop a PCB for ESP8266 WiFi Module. If you remember in the “GETTING STARTED WITH ESP8266 AND ARDUINO” project, I have mentioned that the pins of the ESP8266 WiFi Module are not breadboard friendly.

There, I have made a small perf board for ESP8266 WiFi Module in order to insert it in the breadboard, you could call it a Breadboard Adapter.

Even though this perf board served the purpose of using the ESP8266 on a Breadboard, I still had to connect the level converter resistors, push button to reset the module separately.

So, instead of making a PCB for breadboard adapter, I have decided to make a PCB for the ESP8266 WiFi Module with all the required components like connectors for power, GPIO Pins and communication (RX and TX), slide switch for selecting Programming Mode or Normal Mode, Push button for Reset, headers to insert the ESP8266 WiFi Module and the level converter resistors for the RX Pin of the Module.

Let us start the PCB for ESP8266 WiFi Module by taking a look at the circuit diagram with all the necessary components.

Circuit Diagram

Before proceeding with the PCB Design of the ESP8266 Board, you need to design the circuit diagram with all the components and connections.

The following image shows the circuit connections with respect to the ESP8266 ESP-01 WiFi Module.

I’ll explain the design of the circuit later but first, let us see all the components that are used in the design of the circuit.

Components Required

The following is the list of all the components used to design the circuit of the ESP8266 WiFi Module PCB Board.

• ESP8266 WiFi Module (ESP-01)
• Female Headers (a few strips)
• Push Button
• 1 KΩ Resistor (1/4 Watt)
• 2.2 KΩ Resistor (1/4 Watt)
• 100 nF Capacitor
• Two Way Slide Switch

Circuit Design

First of all, we need to recollect the Pin Configuration of the ESP8266 WiFi Module. The ESP8266 ESP-01 variant has 8 pins, namely: VCC, GND, RX, TX, GPIO0, GPIO2, RST and CH_PD. The pin description is already mentioned in the earlier tutorials.

Coming to the design of the circuit, the VCC and CH_PD pins of the Module are connected to the VCC terminal of the Power Supply header, while the GND pin is connected to GND terminal.

A 100 nF ceramic disc capacitor is connected between the VCC and GND female headers.

The RST (reset) pin is connected to one end of a push button and the other end of the button is connected to GND.

GPIO2 is connected directly to one of the terminals in the female header for GPIO. The GPIO0 pin is connected to the center terminal of a two way slide switch. One end of the switch is connected to the second terminal of the female header for GPIO while the other end is connected to GND.

Next is the communication pins i.e. TX and RX. The TX pin of the ESP8266 WiFi Module is directly connected to the TX terminal of the communication female header. The RX pin on the other hand, is connected through a level converter consisting of a 1KΩ and a 2.2KΩ resistor.

Designing the PCB for ESP8266 WiFi Module

After understanding the requirements and designing the circuit diagram, you can proceed to design the PCB for ESP8266 WiFi Module. I’ve used Autodesk’s Eagle PCB Software for this purpose.

The following image shows a simple layout of the Schematic part of the PCB Design. This image is just a reference and you can draw the schematic as per your convenience using the circuit diagram.

After the schematic is completed, the next step is to proceed with the actual PCB Design. Since this is a DIY PCB, I’ve used a single layer design (although I had to use a jumper at one place).

PCB layout for the ESP8266 WiFi Module is shown in the image below. Once again, this is not a great design but it serves the purpose.

Making the PCB and Assembling the Components

In the “HOW TO MAKE YOUR OWN PCB AT HOME” tutorial, I have already mentioned the necessary steps to be followed for making your own PCB. I would not repeat those steps and instruction as you follow them from that tutorial.

What Factors to consider when you buy a Gaming Mouse

The following are the 7 important factors that should be considered when you buy a gaming mouse.

1. Price

Price is the first and the foremost thing that comes to our mind when buying any product. Apart from the necessity, the price only determines whether you can afford the gaming mouse or not.

If the gaming mouse is within your budget range then you can simply add the gaming mouse to the cart. If you think the gaming mouse you are looking for is expensive or willing to spend less then look for an alternative with the similar features that you wish for.

2. Hardware design

The hardware design is the 2^nd important factor while choosing a gaming mouse. Because the hardware design should exactly match with the fingertips else it is totally worthless.

Whenever you opt for a stylish gaming mouse, check whether it is compatible with the hands and also there should be a smooth movement of the device. It is not necessary that the gaming mouse should be of simple or elegant design. What important is the level of comfort when you handle the device.

Most of the simple design gaming mouse come at very low prices whereas the stylishly designed mice at very expensive prices. Take a wise decision before you consider the design factor that matches your requirements while purchasing the gaming mouse.

3. Durability- Higher the durability higher the performance it offers

Durability refers to the ability of a physical device that retains its functionality without any sort of repairs or the maintenance. In other words, it is also referred as the product capable of technological design and developments.

Here the durability of the gaming mouse explains about different concepts like a color option, battery life, simple nature, technology equipped and the number of clicks. With all the amazing parameters, gaming mouse is said to be the good one.

4. Laser Vs Optical Sensors

The main component used in mouse is the sensor.  All the gaming mice are equipped with the sensor technology and are capable of working on any kind of surfaces compared to the optical mouse. It creates some problem if the mouse reaches the edge of the pad that has higher lift-off distance.

Lasers are more accurate and are high sensitive to dust or other issues under high acceleration. Whereas the optical mice are less sensitive and have lower lift-off distance is the perfect choice for a professional gamer.

And the latest technology equipped with the mouse is the sensor technology. The sensor is considered as the heart and soul of a good gaming mouse that uses IR sensor to lift off the distance and work smoothly on different surfaces.

5. Connectivity (Wired-Wireless)

Connectivity is another important consideration to look for when you own the gaming mouse. All brands offer unified software platforms to have a better gaming experience by synchronizing.

Now-a-day all the gaming mice are equipped with the wireless technology. Its performance is too good when compared to the traditional wired technology and also overcomes the major problems associated with it.

If you really want to make use of the gaming device smartly then go with the Wireless gaming mice that allow the gamer to move freely and operate at a 30-feet distance.

6.Movable range

With the wired mouse, you are able to move the device only to a small area. But the wireless device enables you to move away from the computer. The best part of the movable gaming mouse is that you can move the mouse to any location in the room of range 30-feet and for wired it isn’t possible.

The major disadvantage of using the wired mouse is that you may feel bit irritative and pain in your hands. When you use the wireless mouse, you can comfortably move to any location you wish for, handle smoothly and enjoy playing the games.

7. Battery life

The battery life of a gaming mouse explains the number of working hours it is inactive. The best gaming mouse has the high battery life compared to the regular ones.

Though there are some gaming mice in the market that cannot operate continuously and need to be charged for every couple of weeks. These kinds of devices have a greater performance at the beginning, as the days go on; the performance of the devices reduces to half which makes your valuable money worthless.

So my best suggestion is to buy a gaming mouse that has excellent battery life. If the battery life of the gaming mouse is too good then it can efficiently work on any platform over a long duration.

8. Illumination

Illumination has become the most important feature in recent times. There are some high-end mice whose lights can be configured & programmed to glow at different patterns. The color options of the mouse will not affect or improve the performance of the game but will surely keep the gaming profiles synchronized.

Different Terminologies you should know

Here are few factors that are responsible for a gaming mouse to perform speedy operations very accurately. Check it out…

• Sensitivity

The mouse sensitivity is usually expressed in characters per inch (CPI) or dots per inch (DPI). The sensitivity of a good gaming mouse should be of hundreds to thousands of DPI. If the gaming mouse has high DPI you can move the cursor on the screen quickly.

• Acceleration

In general, acceleration refers to the increase in speed of the object. In this context, acceleration of a mouse is the ratio of pointer speed to the motion of the hand. It is measured in gravitational force (g) which is equal to the 9.8 meters/second.

• Polling rate

It refers to the number of times the mouse is reporting the current position on the computer. It is usually measured in Hertz (Hz) and has a major bearing on the performance.

The polling rate of a gaming mouse may vary between 250-1000Hz. If you send the information via mouse, it first processes the data and then the action is completed on the screen (within milliseconds).

• Programmable buttons

The traditional mice have 2 buttons- 1 left & 1 right and a scrolling wheel. But now they come with many features. Programmable buttons are one among them. They can easily be turned to hotkeys or short keys to execute a specific task.

For example, sniper buttons on the mice help you to shoot the target quickly in a first-person specific game.
