http wrapper for controlling The Internet of Buckets art installation

The Internet of Buckets is a 10x5 stack of buckets with RGB LEDs inside. Each is controlled independently by a microcontroller with its own IP address, which responds to HTTP requests. This module wraps the process of addressing and routing to each bucket.

There are a small variety of demos under examples/.

Usage

Let's draw a gradient:

var draw = require('internet-of-buckets')

for (var i=0; i < 10; i++) {
  for (var j=0; j < 5; j++) {
    var red = 255 * i / 10
    var green = 0
    var blue = 255 - 255 * j / 5
    draw(i, j, [red, green, blue])
  }
}

This will output

API

var draw = require('internet-of-buckets')

draw(x, y, rgb, cb=function noop(){})

Sets a single bucket at (x, y) to the colour rgb.

The top left corner is (0, 0), and the bottom right corner is (9, 4).

rgb is an array of size 3, with values between 0-255. It represents the red, green, and blue components respectively.

If provided, cb is a function that will be called once the write is complete. This can be be useful for e.g. synchronizing several buckets' updates.

Install

With npm installed, run

$ npm install internet-of-buckets
