Hi, I have a sabertooth 2x25 and I would like to control the two motors via a potentiometer that is wired on an arduino duemilanove.
I tried to control the motors just using a potentiometer on the Motor Controller but i get some strange results.
The two motors run on the same speed and direction only when the 10k potentiometer is near its middle value. On every other position the two motors run on different speeds and when the potentiometer reach its final values the one motor runs on its max speed and the other one runs backwards on a slower speed.
Is this supposed to happen?I am a bit confused.
As far as the arduino part is concerned: I try to do the same thing (but with the potentiometer wired to the arduino this time) by sending in serial the values of the pot to the motor controller.
I am pretty new to arduino and Motor controllers and I have a bit of difficulty in making them communicate. have found a library called newsoftserial but I haven't managed to write the appropriate code yet.
Anyone could help? Thank you!
