I would like to track motion with an Arduino, i.e. in an x-y-z space. But I am unsure how to get started. The context that I want to control the way music is modulated later by motion, but as first step, I just want to draw curves of a moving hand.
I could buy an old analog joystick from Ebay, but what would be best to read the (analog ?) signals with Arduino? Maybe this project has been done already too?
We had the honor of getting to meet this kid who created a sign language translating glove using an Arduino an a few sensors. It was outstanding. He did some amazing work for being as young as he was at the time, and it looks like he is continuing to innovate!
