Discover your inner Snow Queen with this temperature sensing pendant. Invoke the elements of snow, air, and fire using your breath or body heat (or your Ice Queen Superpowers). The pendant will display a snowflake, a spinning leaf, or a lovely purple flame animation depending on the warmth of the air. 

Inspired by the elemental spirits in Disney's Frozen II movie, this pendant will be sure to inspire and excite any Queen Elsa fans, and add an element of magic to your cosplay or halloween costume.

This project uses Adafruit's TFT Gizmo, a Circuit Playground Bluefruit, and a 3d printed case. There's no soldering or coding involved -- just a few screws to tighten, and a couple files to upload -- so it's a wonderful beginner project if you're just starting out in the world of electronic cosplay, or if you have a young helper who's getting interested in making stuff.
