For my Mr. Freeze from Arkhym City I want controls. There are lights that light up, there is a face mask that goes up and down. And I want sound effects. So my first plan is a bluetooth keyboard on my forearm, and that talks to a bluetooth shield on a arduino controller. So here is a bread board prototype working with a adafruit bluetooth keyboard. The adafruit controller is super simple, super easy to work with. I have gotten a successfull 3 hours of continuos control of a 1/3 N cell battery. Not bad, I would like 12 hours. I had some spare 1/3 N cell batteries and a socket for it. I think I may need AA's or maybe AAA's. I want to keep it small.
