This is pretty cool – I took the TVout library, the Wiichuck library and wrote a 3D library. Put them all together and got a nunchuck controlled 3D shape on TV. Movement in the nunchuck is detected by the arduino, then the cube is redrawn according to new angle of the controller.
At this point I ran out of memory but it wouldn’t be too hard to set up the shapes in FLASH instead of RAM. The hardware isn’t too complicated, just a few resistors and a pot for the speaker.
Code to tie everything together
