This little circuit is perfect for newbies. I've known this circuit for several years now, but I didn't got the idea of posting it until now.
Step 1: Parts needed
- A DC motor.
- A Double pole a.k.a. DPDT switch. preferably one with a center OFF position, so you can control the motor like this: Forward, stop and backwards.
- A Power supply that suits the specs of the motor (has the voltage and amperage as the manufacturer of the motor recommends). In my case it was 2 AA batteries.
- A Batteryholder (if you use batteries).
- Some wire.
