Overview

Create a delicate ring of NeoPixels attached to a Gemma bracelet. Program your ring in Arduino, CircuitPython, or with MakeCode Maker & then protect your NeoPixels by encasing them in resin.

Make sure you're familiar with the following guides:

Parts

This guide uses an Adafruit Gemma M0 and Nano RGB LEDs. The Gemma M0 should be used with the onboard dotstar LED, capacitive touch sensors, and ability to program using CircuitPython or MakeCode Maker. 

Nano RGB LEDs are a quarter of the size of standard 5050mm NeoPixels you may be used to seeing. They're tiny and adorable and once encased in resin, will be both durable and waterproof. Although these LEDs are not really meant for hand soldering, each LED has a teeny tiny pad that can be carefully soldered to.

The following parts are the electronic parts for the project from Adafruit.
