Hi sorry my first post is a plea for help!
I'd like to control a high power PWM motor controller using my arduino. The MX067 has a potentiometer on the board that is used for the purpose of changing the motor speed. It does this by varying the voltage carried on the wiper between 0 and ~7v. Initially I planned to use a digital potentiometer but I have realsied that the wiper voltage cannot exceed the supply voltage of the IC. (which 6.5v max). Anybody got any ideas for what I can use instead?
(I've tried the hook up an analog output and cross fingers solution to no avail :-[)
