This Instructable further builds upon the previous version
by incorporating wireless buttons separate from the remote. A lap tray with a velcro layer was also created to allow the user to place external buttons where he or she chooses.
The wireless unit utilizes an Arduino XBEE chips to operate.
The Instructable is divided into three sections:
1. Programming the Arduino
2. Building the circuit boards for the wireless unit
3. Wiimote Modification (Receiver)
4. Lap Tray Unit (Transmitter)
