This is still very much (and may always be) evolving, but I’ve been working on a way to help code and test LED patterns in Javascript.

Yeah, it’s called a NeoPixel Emulator, but it’s just a name since it doesn’t use libraries anyway. My hope is that someone far more knowledgeable than I in both Javascript and the FastLED library (or neopixels for that matter) can take a look and branch it off, making for a more robust tool.

I tried to make it so that anything inside the loop function would closely mirror ardunio sketch code so that transitioning would be copy/paste with minor adjustments.

I’m happy to hear comments, concerns and critiques. Enjoy!

AWSOME! I have an inhouse tool i made also in JS for my own LED library! Very nice work mate!

Saw yours Dougal, and it certainly inspired mine, but my goal was to write something that more closely mimicked the arduino and fastLED/NeoPixel code.
