Gamepad connected to computer controls servos connected to Arduino board?

Am I supposed to run the Gamepad Processing code on my computer and the Motor Arduino code on the Arduino board? Running the Gamepad Processing code opens the Gamepad window where I see the sliders move when I move the thumbsticks on the gamepad. After uploading the Motor code to the Arduino, I open the Serial Monitor and the X-CTU window but nothing is happening on either terminal window. The person in the video uses motors controlled by H-Bridge circuit. My robot uses continuous servos. Any suggestions?
