Hey man,
I'd be great if you could do the switch one so i can get an idea of your way or programming and thinking. and i think im also gonna focus more on trying to get Elco Jacob's library to work cus that would probably be easier than trying to write some routine myself ^^. I don't mind on how you'll send me the code, via pm or you post it here, you decide (which is rather logical as you're the one who made the processing sketch:P).
