Crystal Glow Knuckles
This wearable LED glow ring is a great way to get started with the Pro Trinket. It has a LiPo power source, 3 NeoPixel LED's, and a power backpack to charge passively via USB. All the printed components can be generated in a single build without support material.
Prerequisite Guides
Before getting started you should take a look at the Adafruit guides that cover the tech we'll be putting inside this ring.
