This example shows different ways to use AnimationGroup: syncing four animations across two separate
pixel objects such as the built-in NeoPixels on a Circuit Playground Bluefruit and a NeoPixel Ring.
This example is written for Circuit Playground Bluefruit and a 16-pixel NeoPixel ring connected to
pad A1. It does not work on Circuit Playground Express.

After downloading the Project Bundle, plug your Circuit Playground Bluefruit into the computer USB port. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called CIRCUITPY. Unzip the folder and copy the following items to the Circuit Playground Bluefruit's CIRCUITPY drive.
- lib folder
- code.py
Your Circuit Playground Bluefruit CIRCUITPY drive should look like this after copying the lib folder and code.py file.
