Overview of this book

This book employs an incremental, step-by-step approach to get you familiarized with everything from the basic terms, board components, and development environments to developing real projects. Each project will demonstrate how to use specific board components and tools. Both Galileo and Galileo Gen 2 are covered in this book.

Launching random LED animations

The one thing that we'll want to do while the videos are playing is to play a random LED animation. To do so, we'll create a new file and develop some methods to help us handle those animations.

The idea is to have a method to stop and set the strip off and the other to select a couple of colors and play an animation, switching between those colors randomly.

To control the LED strip, we will use the lib UPM jsupm_lpd8806 and to loop between the strip LEDs, we will need to use the async module, which will provide us with asynchronous loops. Together with the setTimeout method, this will help us keep the process non-blocking.

Firstly, let's start by installing the async module by typing npm install async inside the project folder (chapter7). When it finishes installing, create a new file by typing vi animations.js and paste the following code:

var LPD8806 = require('jsupm_lpd8806').LPD8806;
var async = require('async');

var stripLength = 30;
var ledstrip = new...
