Figure 26—A Nintendo Nunchuk controller
Wiring a Wii Nunchuk
Wiring a Nunchuk to an Arduino really is a piece of cake. You don’t have to
open the Nunchuk or modify it in any way. You only have to put four wires
into its connector and then connect the wires to the Arduino:
It has six connectors, but only four of them are active:
GND, 3.3V, Data, and Clock. Here’s the pinout of a
Nunchuk plug:
Put a wire into each connector and then connect the
wires to the Arduino. Connect the data wire to analog pin 4 and the clock
wire to analog pin 5. The GND wire has to be connected to the Arduino’s
ground pin, and the 3.3V wire belongs to the Arduino’s 3.3V pin.
