Taiko Synth - Phase 2

The sythesizer produces lots of different sounds. I need and easy way to select a sound an listen to it.

There are 127 voices, 127 notes, and 2 different channels.


A Nintendo Wii nunchuck is used to select voices, notes, and channels. It also is used to play the selected sound. An adapter is needed to connect to Arduino.

Solder a header to the adapter and plug it into analog inputs 2-5. The "Wire" library will use the use analaog inputs 2 and 3 for power and inputs 4 and 5 as digital i2c I/O.

For a nunchuck libary that makes the interface really easy, here's a link to Todd Kurt's blog.

Download the Wiichuckdemo. Put the example program and nunchuck_funcs.h in the same sketchbook folder and open them together with the Arduino IDE.

Compile and upload to the Arduino to make sure everything works.
