Build your own glowing LED bubble wand with Adafruit's Mini Sparkle Motion controller and waterproof LEDs. We provide the 3d printable files and detailed instructions on how to assemble the wand, and even tell you our secret recipe for giant bubbles. This project uses WLED, a free, open-source LED control program. Control the lights on your bubble wand using your smart phone or any web browser over WiFi.
