We take a look back at this 2018 project from Sparkfun. With temperatures hitting record lows this winter, why not warm your ears with these cute light-up earmuffs.
In this project, we’ll create a wearable pair of heated earmuffs with decorative addressable LEDs. These earmuffs are embedded with a Pro Micro 5v, two heating pads, and four rings of WS2812 addressable LEDs, or ‘Neopixels’. This project is designed to keep the user extra warm while still looking stylish.
