Project Description
The Neopixel pendant was something that I built for an older family member of mine. Her favorite color is purple and it gave me a chance to work with the Arduino IDE. For this project I used the Adafruit Gemma, Lilypad Coin Cell Battery Holder, Lithium polymer battery, on/off switch, Pro Trinket charging backpack and the hollowed pendant.
