+// Simple example application that shows how to read four Arduino
+// digital pins and map them to the USB Joystick library's hat switch.
+//
+// The digital pins 4, 5, 6, 7, 8, 9, 10, and 11 are grounded when 
+// they are pressed.
+//
+// Pin Mappings:
+//   4 - Hat Switch #0 UP
+//   5 - Hat Switch #0 RIGHT
+//   6 - Hat Switch #0 DOWN
+//   7 - Hat Switch #0 LEFT
+//   8 - Hat Switch #1 UP
+//   9 - Hat Switch #1 RIGHT
+//  10 - Hat Switch #1 DOWN
+//  11 - Hat Switch #1 LEFT
+//
+// NOTE: This sketch file is for use with Arduino Leonardo and
+//       Arduino Micro only.
