Hey guys I'm new to working with LEDs but I randomly decided this would be my halloween costume. Please help me electronics or otherwise on what I would need to pull this off down to the amount of LEDs and stuff like that I would need. If you have the time some instructions or a diagram would be great. And(for lack of a better term) please put your responses in "dumbed-down" talk. Thanks.
PS If you dont think arduino would work well but you have other ideas let me know.
