How to Control a DC Motor to Run in Both Directions

Those H-bridges are very useful and smart, but if you just want to control the direction of the motor with a switch (manually), there is a much simpler and cheaper alternative.

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.

The parts, you need to make this can be found in any electronic store, or even lying around in your workshop (if you have any).

You'll need:

• 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.

I don't think, this could be easier. Just follow my pictures.

When I learned to make this circuit (I think I was 9 years old) I made a simple, little car that could drive forwards and backwards.

Now all you newbies out there: go make some creative with this circuit and post some pictures of it.
