The Wii Nunchuck has proven to be an excellent bargain - switches, joystick, and accelerometer in one handy package! But it's a shame to hack off the connector to make use of it, so use the Solarbotics Nunchucky breakout board adapter!
The Nunchucky features:
- Two sets of interface pads
- Includes a 4 Pin male header
- Lock notches so your Nunchuck "clicks" in and won't let loose!
- Tie-down Holes for securing ribbon-cable extensions
Pairs perfectly with our Wii Nunchuck controller
You'll need a microcontroller with i2c port, there is lots of example code online, we like this Arduino sketch
Please note that some people have reported problems with cheap 3rd party nunchucks not working with Arduino sketches.
