Ok, I already know this is WAY over my head already, but I want to build a light display using multiple LED's. The problem I am facing is I can't seem to find any controllers that interface with a PC that will tell me how many LED's they will drive. They tell me how many channels they have, but never how many LED's the controller will drive per channel. Is there a universal amount of LED's able to be run on say a 16 channel controller? Any help would be very appreciated. Also, if anyone has a schematic of a large scale controller, or even a small scale controller that can be PC based, if you are able and willing, I would love one. I know a little about electronics but I have a LOT more to learn. If it's not the most difficult schematic to follow, I might be able to build one, and save myself a ton of green. Thanks for any help you might be able to lend.
