Adafruit motor controller & Arduino Mega ADK w/USB - reroute pin 7 in software??

Using Arduino Project Guidance
3

What you will need to do is:

  1. Break the connection from the motor shield to digital pin 7 of the Arduino. The easiest way to do this is to cut off that pin on the bottom of the motor shield.

  2. Connect that pin on the motor shield to an unused pin, for example pin 13 or one of the analog pins. You can do this by connecting a jumper between pin 7 and your chosen pin on the top of the motor shield.

  3. Modify the motor shield software to redefine MOTORENABLE as your chosen replacement pin.
