Running the motor:

1. Firstly, ensure that all connections are secure! Make sure that nothing is falling apart or will disconnect—this is crucial as if anything disconnects it could fry a component

2. Close the switch—you’ll know it’s on if the digital ammeter lights up

3. Connect PWM pins 5 and 6 from the Arduino to AN2 and AN1 respectively and the connect the Arduino GND to the Motor Controller GND

4. Find the remote control and turn the motor controller on—you’ll know it’s on if the controller’s fans turn on and the PWR LED is lit green

5. Connect the computer with the appropriate ROS motor code to the Arduino

6. Run the ROS motor code and watch the wheels turn

Possible errors:

• The Arduino isn’t loaded with the right code: Just reload the Arduino with the right Arduino-ROS code (in the ART Embedded Repo) and check the connections again
• Power to the motor controller: It’s possible that the switch control on the side of the motor controller is not connected correctly. Just take a jumper wire and connect the the two ends of the switch and see if the motor controller turns on. If it does, run the tests you need to and make a note about the switch problem, but if it doesn’t, it’s likely that there is a problem with the motor controller (make a note of it)
• If it’s neither of the above, check connections again
• If that still fails, check the switch configure located near the DIG, AN pins on the back of the motor controller: Be sure that it’s in a setting of 10110000 (if this setting doesn’t work then try 10000000)
• If all of the above fails, message me, Jason, and I will do my best to help figure out the problem
