This time around he’s explaining H-Bridge motor controllers and how they work! Even if you don’t have much (or any) experience with basic electrical circuits, [Afroninja] explains the concept ...

We can see how circuits work, and represent them with some simple diagrams, using basic electrical components ... to be powered by the cell. Like a motor. Or you can even put in a switch that ...

Next he demonstrates stepping the motor manually and then makes a simple FET driver circuit. Just when you’re expecting a small microcontroller to appear, the [IMSAI Guy] instead digs deep into ...
