Build a Motion-Detecting ‘Scream Box’ Without any Microcontroller or Code #ElectronicHalloween
Assemble this ‘Scream Box’ for Halloween (or just because!) and frighten trick-or-treaters when they approach your door or open the box; the PIR sensor will detect their heat presence and activate the circuit, which uses an Audio FX board that requires no microcontroller programming or code on your part. Just plug and…screaammmmm!!
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!
HAPPY HALLOWEEN! Every day this month we’ll be bringing you ideas and projects for an Electronic Halloween! Expect wearables, hacks & mods, costumes and more here on the Adafruit blog! Working on a project for Halloween this year? Share it with us on Google+, in the comments below, the Adafruit forums, Facebook, or Twitter— we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). You can also send us a blog tip! Tune in to our live shows, 3D hangouts with Noe and Pedro and Ask an Engineer, featuring store discount codes, ideas for projects, costumes, decorations, and more!
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.

Ooo! I’m doing something similar, just one step more complex. The motion detector is hooked to an Arduino. When triggered, it plays sounds through the Sound Board via UART mode while also lighting up LEDs.
The LEDs are in three hollow jack-o-lanterns, lighting them up. The pumpkins are in a row, with stereo speakers at each end. By pre-panning sound clips to the left, center, or right, I can make the sound seem to come from any of the jack-o-lanterns, which are lit up appropriately to match the sound.
