Intel Edison Projects

Overview of this book

Change the way you look at embedded electronics with Intel Edison. It is a small computing platform packed with a set of robust features to deliver hands-on performance, durability, and software support. This book is a perfect place to kickstart development and rapid prototyping using Intel Edison. It will start by introducing readers to the Intel Edison board and explaining how to get started with it. You will learn how to build a mini weather station, which will help you to acquire temperature and smoke level and push it to the IoT platform. Then you will see how to build a home automation device and control your appliances using an Android app. Furthermore, we will build a security system using a webcam to detect faces and perform voice recognition. Toward the end, the book will demonstrate how you can build two robots, which will be based on different line sensing sensors and can be controlled by a PC. The book will guide the readers through each and every step of execution of a project, using Intel Edison.

Getting data to Edison by using MQTT

We have been talking about home automation controlling electrical loads, but everything has a starting point. The most basic kick-starter is controlling Edison over the Internet—that's what it's all about.

When you have a device that is controllable over the Internet, we recommend controlling the electrical loads. In this other mini-project, we are going to control a simple LED that is already attached to pin 13 of Intel Edison. There is no need for any external hardware for this, as we are using an in-built functionality. Now, open your editor and type in the following code:

var mraa = require('mraa'); var mqtt = require('mqtt');

varledPin=new mraa.Gpio(13); ledPin.dir(mraa.DIR_OUT);

var client = mqtt.connect('mqtt://'); client.subscribe('avirup/control/#') client.handleMessage=function(packet,callback)
