From the MAKER: Basically, I wanted to build some kind of LED matrix driven by an Arduino and laptop for some kind of Halloween costume this year. I ended up using Disney’s Electrical Parade song as the inspiration for my costume. As you can see from the video, the matrix cycles through random animations but when I press a button on my wireless keypad, it starts to play the Electrical Parade song along with some (somewhat) synchronized visuals. I haven’t had time to document it all yet, but I plan to after Halloween.
