Do you need a last minute Halloween decoration to scare your friends and trick-or-treaters? Try building a scream box that lets out blood-curdling screams when it’s opened! By using a passive infrared (PIR) motion sensor and an Audio FX board you can build this scream box without even using a separate microcontroller or writing any code!
Before you get started it will help to familiarize yourself with the following guides:
Audio FX Sound Board Guide
PIR Motion Sensor Guide
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
