NeoPixel LED Simulator

Demo: https://1000hz.github.io/neopixel-simulator

Here's a little simulator to help sketch out LED animation functions for one of these things: https://www.adafruit.com/products/2875

Usage

The library includes some LED Modules (currently only NeoPixelRing60). These accept a callback to run on each render tick. The callback is passed an array of blank Pixel(r,g,b,w) instances, and the current tick. It must return an array of Pixels to be rendered.

You'll also need to instantiate a Simulator class. Simulator constructors take LED Modules as arguments. After you've instantiated your Simulator, call simulator.start() to begin the light show.

const neopixel = new NeoPixelRing60((pixels, t) => {
  return pixels.map(p => new Pixel(255, 255, 255, Math.random()))
})

const simulator = new Simulator(neopixel)
simulator.start()
