In this project we'll build an interactive cardboard fireplace with LEDs and a motorized Grinch!


A Circuit Playground Express will drive an LED strip and a servo controlled paper Grinch cutout. Hidden under a rug, a simple switch  triggers the servo when stepped on. So the Grinch looks like he's hiding when someone steps on the rug, sneaky!

NeoPixel Fire


Build a fire using paper towel tubes and other packaging material. Use a NeoPixel LED strip to create animated lighting effects!


All of the electronics are easy to put together and no soldering is required! The neopixel strip and motor connect to the Circuit Playground with alligator clips, so it easy to assemble and change the theme of the fireplace!
