First of all, I can control Arduino from iPhone by using Processing and TouchOSC app.
But my task is to achieve a control wirelessly "without using a PC" in between. I need to control Arduino directly by iPhone via "wifi". I should only use an Arduino, a shield, an iPhone and the wifi network. This is the task i am given.
I am really confused which way to use and which shield to buy.
I would be so glad to have your opinions.
