Many types of circuits are useless and less useful if you cannot control the amount of power going through them. For that, you need a PWN (pulse with modulation) switch. This electronic component will let your control the power going through the circuit, enabling you to dim LED lights, control the speed of a motor, and other useful tasks. This video will teach you all PWN switches and how tom make your own.
