 6  This example shows different ways to use AnimationGroup: syncing four animations across two separate
 7  pixel objects such as the built-in NeoPixels on a Circuit Playground Bluefruit and a NeoPixel Ring.
 8  
 9  This example is written for Circuit Playground Bluefruit and a 16-pixel NeoPixel ring connected to
10  pad A1. It does not work on Circuit Playground Express.
