Project 1: LED 8x8 Matrix Game

------------ Snake Nunchuck -----------------

Classic snake game implemented on Arduino.

Uses the Wii Nunchuck joystick as the interaction device. User moves around the grid and eats the food which is running all over the board.

The game ends when the snake eats itself.

------------ Wii Nunchuck ------------------

I used the "WiiChuck" Wii Nunchuck Adapter:

The most recent WiiChuck library can be found at:

https://github.com/todbot/wiichuck_adapter

The WiiChuck communicates over I2C which uses the SDA and SLC pins (A4 and A5) to communicate with the Wii Nunchuck.

The Wii Nunchuck has a triple-axis accelerometer, two buttons, and a joystick. The joystick is implemented using two potentiometers and thus gives you the ability to read input for any angle.

Simply copy "nunchuck_funcs.h" into your project folder and #include "nunchuck_funcs.h" it in to get access to the functions.
