I found this Arduino project really interesting and educational. They used several different techniques to get everything to work properly. I love the disclaimer of “way too many technologies”. How true! However, it’s not always about the practicality of a project, as much as it’s about the process and documentation.
Here’s my latest project. It involves way too many technologies for the sole purpose of controlling iTunes with Wii Nunchuck. Signal flow is almost uni-directional, so let’s go from step by step from the Nunchuck to iTunes.
