You're attacked by a Repair Nektann

I imagine the logic for what you want to do is pretty easy, it's just a matter of the syntax. Try writing up what you want to do in pseudo-code and then read some Arduino guides to find examples of turning on LEDs, then just copy and paste and debug (and debug and debug).

I already know someone who's been programming some basic Arduino stuff (he's the one who turned me on to the idea in the first place) so he could probably help me with that, the issue I'm running into is how to then connect it to TouchOSC so I can control it from my iPod.

The easiest way would be to have a loop that's listening on a port/connection/however it's abstracted in the language. If it hears something from the iPod, it executes the appropriate function, then goes back to listening.

Well I've managed to set up a Processing document that takes commands from the app. Now I just have to convert that to an Arduino program to have the Arduino turn on LEDs instead of highlighting triangles and squares.

 

 

e: so actually I may have figured out a way to do this, yay
