Pulse Width Modulation (PWM) tutorial

PWM circuits are fun. You can use them to dim LEDs, control the speed of fans and motors, control the power going to a thermoelectric cooler, or control the power going to pretty much anything you want. Just make sure that you don't exceed the maximum voltage rating of your device. The video explains it all.
