#014 AsyncLedStripEffects

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


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.

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

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 (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
