Want to hook up a Wii Nunchuck to an Arduino but donâ€™t want to cut up the cord on your Nunchuck? Yeah me too. So I made some of these… Itâ€™s a small PCB that adapts the Wii Nunchuck connector to standard 4-pin header. I call it the â€œwiichuck adapterâ€. It plugs directly into the Arduino, no wiring necessary. You can get one too for $3.
One of the coolest things about the Wii (to me) is that the expansion port on the bottom of the Wii remote is an I2C serial connection. This means that anything that plugs into that port can work with microcontrollers like the Arduino. Of the available peripherals, the Wii Nunchuck is one of the best. It contains a 3-axis accelerometer, a 2-axis joystick, and two buttons. Hooking up a Wii Nunchuck to Arduino is easy and Iâ€™ve have class notes describing how to do it. But cutting off the connector of the Nunchuck to get at the wires is a little drastic.
This â€œwiichuck adapterâ€ letâ€™s you play with the Wii Nunchuck and other Wii remote peripherals without needing you to cut cables. Just plug it into the Wii Nunchuck, then into the Arduino.
