Create glowing eyes for your costume! This project is ideal for any character with glowing eyes, like the Black Mage from Final Fantasy, Jawa from Star Wars, or Orko from He-Man. Two NeoPixel Jewels can appear any color or animating pattern, and they are driven by a GEMMA microcontroller powered by a 500mAh lipoly battery in a 3D printed pocket.
This guide was written for the 'original' Gemma board, but can be done with either the original or M0 Gemma. We recommend the Gemma M0 as it is easier to use and is more compatible with modern computers!
