The controller is made up of an Arduino (bottom board), a Wave Shield (middle board) from Ada Fruit and a prototype board (top board) outfitted with an RF receiver (side ways on the top board). The Arduino is the brains of the outfit and allows me to program the behavior of the setup. The Arduino processes all the signals and, based on the firmware I wrote, will act accordingly. The Arduino talks to the Wave Shield to play audio files from an SD card on the Wave Shield. The Arduino also controls 6 relays which control the lights, fog machine and values which allow air into 5 pneumatic cylinders. The cylinders then will shake the crate, bang on the crate, lift the lid, and pop the gorilla mask out in two stages, first up then out. More details will follow...
