Hey. Quick question: Does anyone know if it exist high current digital potentiometer you can control with arduino?
Those I find usually use the same current and voltage for input and output. I am currently looking for something that would withstand 10A. And controllable with arduino.
I am going to use it for a coil, i am using PWM and some transistors now. I just burned my IRF520 transistor :P so would like some alternatives.
