Essentially I have a fully working project which has a typical PSU to PWM to (very large) Motor. All that I need to control here is the speed of the motor and the on off switch. Currently this is being done by turning a pot (10k) on the PWM and using a rocker switch (tada!) I now want to adapt thi…

Arduino to control existing PWM board?

Thanks,

Is it ok that either side of the digital pot ie the Arduino and the pwm are on separate circuits?
