Hi all, I use Arduino uno with motor shield Pololu. Programmed with DCC++ base station software and communicating via DCC++ controller. All works well. The one problem I have is that the current feedback is not working, I can't see any current drawn on the screen. I understand that the current feedback is done via A0 & A1 pins, do I need to use a resistor on motor shield before the signal goes back to Arduino Uno? Could you please advise. Thank you. Rudolf.
