Wii Nunchuk as Mouse, Keyboard and Gamepad

Wii Nunchuk as Mouse, Keyboard and Gamepad

I put a Teensy 3.1 in the Nunchuk and hooked up the existing buttons and the joystick to it.
I added 4 more buttons.
The nunchuk has 3 modes. In the first mode the joystick is a mouse, in the second mode the joystick acts as the arrow keys of a keyboard and in the third mode, the nunchuk is a one-handed gamepad.
