how to control the speed of a motor

Hi
I have a 12v motor and a arduino uno

I need to control the speed and direction of the motor from the arduino
I have googled and used previous knowledge of electronics and I am still stumped

Any ideas would be greatly appreciated

Thanks
Joe

Hey

I think a H-bridge motor controller using PWM pins to control the speed is what you need from your requirements.

Here a tutorial for a H-bridge motor controller:

You may want to use a very small motor while your developing so you can run it off your arduino uno.

Hope this help and gives you the ideas you need for your project.

Note: If you need additional help maybe you should post this in the arduino fourm or the arduino section on this site. as you may get a faster response
