I have the DROK® Micro DC Speed Controller 10-60V 40A PWM Motor Controller Speed Regulator Module Board with Start/Stop/Brake Switch Adjustment Potentiometer
how do I get it to be controlled by 0-5V from an arduino
when I measure the pot none of the sides are ground… so the main power ground is not in common with the pot 0-5v..
tell me how to hook it up to an arduino with common ground.
you claim that its controllable from a PLC.. show me how
thanks
