CHAPTER 3
Nunchuk-Mouse
This chapter’s project is about attaching the Nintendo Wii Nunchuk to the Raspberry Pi. The Nunchuk has two buttons; an X-Y joystick; and an X, Y, and Z accelerometer. The sensor data is communicated through the I2C bus. Let’s have some fun using a Nunchuk as a pointing device for the X Window System desktop.
