#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:

AsyncLedStripEffects - using a timer interrupt to run effects on an LED array

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.

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
