I am trying to see / verify the output from the acs712 motor current sensors. The output from the sensors is connected to A0 and A1 pins on the megga. Can any tell me in ArduRemote or in the serial monitor where is the output of these sensors displayed. Also what would be normal values for forward and reverse at 50rpm.
I am using small 12 volt motors. I doubt that they ever pull 5A more like 2A. I understand from the ACS712 data sheet that the output is 66 mV per amp. So from -5 to + 5 amps the voltage range will be 2 volts. When I test forward and reverse I only get 15mv difference.
