I have an Arduino Uno R3 with which I have done some simple projects for getting into MC programming. I am looking for a way to have my iPad control lights via DMX. The iPad has no possibility for a wired DMX output connection, so I have three other options:
Use an iPad MIDI interface and convert the MIDI signal to DMX That's a bit tricky, because MIDI messages have only values 0..127, DMX has 0..128. Besides, I cannot use the Pin connector for powering the iPad, so I would by limited by battery life.
Use Arduino for receiving messages over Wifi to convert to a DMX output Complicated and the Wifi shield is quite expensive
Use Arduino for receiving messages over Bluetooth to convert to a DMX output That is the solution I am looking for. Is it technically possible to receive Bluetooth messages and simultaneously generate a DMX output signal? I have found some Arduino DMX projects with a MAX485, so output alone should not be a problem.
