Ah, Halloween. A fun time to hand out candy. Also, a very fun time to scare trick-or-treaters!… But how to combine the two? The Screaming Cauldron allows you to do both at the same time!
By using an infrared distance sensor to determine hand proximity, the Trinket M0 microcontroller adjusts the light colors and then lets out a bloodcurdling, amplified scream at just the right moment!
Build your own — or any other proximity-based sound/light effects — using this simple project! You’ll have it wired up in no time, and the CircuitPython code is very simple to adjust to suit your needs.
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, Discord, Instagram 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, 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.
