Turn every step into a burst of light with these interactive light-up children's animal slippers. A force-sensitive resistor tucked inside the insole detects steps, and instantly triggers animations across addressable NeoPixel LEDs, glowing in your favorite colors. As you walk, the slippers respond in real time—adding a playful, responsive layer of light to every step. Comfortable, customizable, and full of personality, this project brings wearable tech right to your child's feet.

This guide uses a Feather PropMaker RP2040 board, and we've included sample CircuitPython code to get you up and running. Customize the code to make the colors and animations exactly what you want them to be, and let your animal spirit shine through.

For two slippers you'll want to order two controllers, two resistors, two switches and two batteries. 1 meter (39 inches) of NeoPixels was enough to surround both of the little tyke slippers I made.
