Nunchuck via Jason Barnett Multichuck

Only available in ScratchGPIO6 Alpha

The Nintendo Nunchuck is basically an I2C device and can be connected cheaply and easily to a Pi using a Multichuck.

It then adds a joystick with 2 buttons and a tilt sensor for Scratchers use in their projects.

Once plugged in, additional sensor values available are:

NunchuckDocsButtonC – On/Off

ButtonZ – On/Off

joystickx left/middle/right

joysticky up/middle/down


tiltx -90 to +90

Note: angle is the last angle the joystick was pushed to not its current position
