Hi all, I would like to use and Arduino to replace the 0-5V 10K analog potentiometer that is currently used to control the speed input on a DC motor controller. Additionally, the Arduino and the 0-5V speed control input must be isolated. I have tried using a digital pot (MCP4131) but it is acting e…

Hi,
Can you post a diagram of how you have the Arduino, what model, and the digital pot and motor controller please?

Can you please post a link to data/specs of the motor controller?
