So I've asked this before, but I'm moving forward with it and being more clear about what I want (hopefully). I want to have a lighting setup for this band. The idea is that there are 9~ paper lanterns on stage with them, and each lantern has an array of RGB lights inside. Within each lantern, each RGB LED is doing the same thing, so they can all be connected without worrying about independent control, make sense? However, each individual lantern needs to be able to be controlled individually. So lantern A might be BLUE, while lantern B might be RED, or OFF. I would control this from an iPad, which sends OSC to MAX/MSP, which communicates via serial to Arduino. I already have this part working, sort of. I can control a single RGB LED from an iPad, run thru MAX to Arduino and it works just fine. However, obviously Arduino has limited outputs, so I can't have 9 RGB signals (9*3 outputs?) from a single Arduino. What is the easiest, most efficient way to do this project? Keep in mind that I am somewhat new to Arduino and electronics!
