This box makes scary noises and has glowing red eyes that turn on when the lights go out. Put it under a bed or desk to prank your friends (or colleagues)!
You could also change the type of sensor to make a motion- or proximity-activated monster for a haunted house.
The box contains an Arduino Uno, a recording/sound module, a servo, and a pair of LEDs. A phototransistor lets you measure the light in the room and know when the lights go out.
