I have a toy usb robot arm which I have added potentiometers to and ran the 4 dc motors into the adafruit motor shield in points M1- M4. My potentiometers are reporting back to my VB.NET application just fine using FirmataVB and StandardFirmata on the arduino, I can control my robot arm in one direction with the test application on the output with digital pins but only in one direction.
Where do I start looking for the code to edit in order to make this able to run the DC motor in both forward and reverse given the variable, or is there something obvious I am missing? Has someone done this already? I can't find anything on it!
Thanks a lot for your time guys.
