Running Drive Program on EXP Brain

The Drive program is a default program built into the VEX EXP Robot Brain so it can be used with Smart Motors, Sensors, and the VEX EXP Controller without programming. The Drive program maps the Controller’s joysticks and buttons to control specific Smart Ports on the Brain.

Step 1: Check that the Smart Ports are properly wired.
