Led Animator

Installation

npm i @mathquis/node-led-animator

Usage

const Leds = require('@mathquis/node-led-animator')

const NUM_LEDS = 16

const render = leds => {
    const buffer = leds.toBuffer()
    console.log(buffer)
}

const leds = new Leds({
    leds: NUM_LEDS,
    startAt: 0,
    onRender: render
})

// Create some colors
const orange    = leds.createColor(255, 128, 0, 255)
const red       = leds.createColor(255, 0, 0)
const green     = leds.createColor(0, 255, 0)
const blue      = leds.createColor(49, 196, 243)
const darkblue  = leds.createColor(35, 61, 83)

// Use these colors
leds.setColors([orange, blue, green, orange, red])

// Animate them
const step = 1
const speed = 60 // ms per frame
const iterations = 3
const cb = () => {
    console.log('finished')
}
leds.rotate(step, speed, iterations, cb)
