These are the snowflakes we designed to go with this project-- we sketched them out as bitmaps in Photoshop and then coded little snowflake functions using the GFX library for Arduino.
All the code resides in GitHub in this repository.
There are three sets of code:
- A basic test program, no Bluetooth,
- Using a Feather 32u4 Bluefruit and
- Using FLORA and the FLORA BLE module.
See the following pages for each variant. Download the code that matches your board (Feather or Flora), then open up the .ino file inside that folder with Arduino.
