// Simple gamepad example that demonstraits how to read five Arduino
// digital pins and map them to the Arduino Joystick library.
//
// The digital pins 2 - 6 are grounded when they are pressed.
// Pin 2 = UP
// Pin 3 = RIGHT
// Pin 4 = DOWN
// Pin 5 = LEFT
// Pin 6 = FIRE
//
// NOTE: This sketch file is for use with Arduino Leonardo and
//       Arduino Micro only.
