|
This example shows three different ways to use AnimationGroup: syncing two animations, displaying
|
|
two animations at different speeds, and displaying two animations sequentially, across two separate
|
|
pixel objects such as the built-in NeoPixels on a Circuit Playground Bluefruit and a NeoPixel strip.
|
|
|
|
This example is written for Circuit Playground Bluefruit and a 30-pixel NeoPixel strip connected to
|
|
pad A1. It does not work on Circuit Playground Express.
