#014 LED Array Async Effects

Demonstrates timer-interrupt triggering of addressable LED array effects using the FlexiTimer2 library.

Here’s a quick video of the demo:

Notes

When running an animation sequence on an LED array, we don’t want it upset by other processing on the Arduino. This sketch uses the FlexiTimer2 library to drive the effect sequence from a timer interrupt. That leaves the main loop() for doing other things.
