Understanding Gamepad Controllers - Dutton-Christian-Robotics/Learning-to-Code GitHub Wiki

So far we've only looked at autonomous opmodes where we determine in advance what the robot should do. But that's only a portion of an FtC game. How do we make the robot do what our driver and manipulator want it to?

Opmode objects come with two property variables, gamepad1 and gamepad2, each of which gives the ability to determine what buttons or sticks are pressed on the controller.
