hey thanks for the reply,I have already successfully connected ipod(touch osc) with arduino via wishield 2.0 without the need for Processing, so it can be done without the need for a computer. So thats not a problem, what I am trying to do is to somehow send messages to the ipod via the wishield, for example,If a sensor is triggered it will send a message to the ipod to turn a led on, on TouchOSC,or change the position of a fader on touchosc
