Valentine’s Day is right around the corner so get making for that speceial someone. This project shared by Hackaday from Heliox on YouTube is a set of wirelessly controlled LED hearts.
Yes, [Heliox] has built a Valentine’s day project, and the presentation is top notch as always. A heart is 3D printed in white filament, with two chambers separated by a thick wall. Each chamber features five NeoPixel LEDs, controlled by an ESP8266 in the base. The color of each chamber can be controlled through the Blynk smartphone app, allowing you to choose the exact colors that best represent your relationship.
