Joystick_Serial_test.ino

// Simple example application that shows how to read four Arduino
// digital pins and map them to the USB Joystick library.
//
// Ground digital pins 9, 10, 11, and 12 to press the joystick 
// buttons 0, 1, 2, and 3.
//
// NOTE: This sketch file is for use with Arduino Leonardo and
//       Arduino Micro only.
