Fun to build, hard to explain

Astable multivibrator on a breadboardA circuit that many see early on is this one:

The astable multivibrator.

It’s not an inviting name, but definitely a fun circuit to build!

The astable multivibrator is a classic circuit for flashing two LEDs.

Or it can create a tone to play on a speaker.

Here’s the circuit in action:

I had so much trouble understanding this circuit when starting out.

And it frustrated me because I was thinking it was a simple and easy-to-understand circuit.

But the truth is that you need to have a good understanding of the basics of electronics before you will be able to understand it.

This is a hard circuit to explain because there are many things to think about at the same time.

But I did my best, and here’s the result:

Keep On Soldering!
