A következő kis programocska a Wii Nunchucku Arduinohoz való illeszkedését hivatott bemutatni. Ezzel kapunk egy teljes értékű joystickot amit a később még játék vezérlésre is fogunk használni.
A csatlakozásokra érdemes figyelni, és az Arduino Mega csatlakozásait írom le:
- + to +3.3V
- – to GND
- SDA (pin 20) – képen a sárga
- SCL (pin 21) – képen a zöld

/*
Arduino sketch to demonstrate interfacing with a Nintendo Wii Nunchuck. It will print the nunchuck information from P1 every second, to the serial terminal at 9600 baud.
