Built a Halloween pumpkin with LEDs + motion sensor. Kids screamed (good)

Electrician hobby project for Halloween. Cheap motion sensor, a small microcontroller, and red LEDs inside a plastic pumpkin. When someone walks near the gate, the eyes glow and it plays a short laugh.

First try with the neighbor kids: two screamed, one asked how it works. The one who asked how it works will become an engineer, I think.
