Test the microcontroller, shield, and motor system using the example program provided by Adafruit called Motor Test found in the AFMotor folder under examples. Only one modification is needed to use this program, and that is to change AF_DCMotor motor(4) to AF_DCMotor motor(1), since we are not using motor terminal 3 and 4. Once the program is uploaded and the motors active, make sure the command of forward matches forward motion of the wheel, backward matches reverse, and release matches pause. Also, make sure the motor speed ramps up and down. If so, your motor system is OK to move forward in the project. If not, adjust motor lead until these functions match the command. After this program, modify the program for motor 2 and repeat test.
