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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
