Screaming Cauldron #ElectronicHalloween

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.
