Would it be possible to control a wheel chair motor with a dimmer switch for speed control and a 3 way switch for forward and backward movement. If it were possible, then couldn't you have a servo flip the switch from forward to reverse and another servo turn the dimmer switch nob for speed control?
yup, i would suggest something such as a transistor+relay hooked up to a digital pin on your microcontroller...or better yet, a motor controller controlled with pwm! that would replace the whole circuit!not to mention being more reliable than the mechanical counterpart...

How would this work with just a motor controller controlled with pwm? I am looking to try to control motor shaft direction using a controller and not a motor driver.
It wouldn't, unless the controller has got an in-built driver. A motor driver is what goes between a controller and a motor to put out the needed current.
Didn't the equipment come with a manual?
No, they just came with a piece a paper showing each component of the board.Here are the links to the devices on sparkfun.com
Yes, they I know the Motor driver is bidirectional but I also need the motor controller to limit rpms of the motor's shaft. I was just wanting to know how to connect the motor driver and controller together so I can limit the shafts speed and using both directions.
But the RPMs are just too great. Is there a way to decrease the output voltage and hopefully that will slow down the rpms?
