Motion Sensing Skull Prop

This halloween prop uses a PIR motion sensor to detect movement, then sends a signal to an arduino with a wave shield which makes the LED eyes blink rapidly and plays a scream wav file from an SD card using a Tivoli PAL. I used a branch from a tree to mount it eye level for kids and some cotton spider webbing to hide the wiring. The arduino and 9v battery pack are in a black enclosure and can be hidden in nearby bushes.
