Building Smart Homes with Raspberry Pi Zero

By: Marco Schwartz

Overview of this book

The release of the Raspberry Pi Zero has completely amazed the tech community. With the price, form factor, and being high on utility—the Raspberry Pi Zero is the perfect companion to support home automation projects and makes IoT even more accessible. With this book, you will be able to create and program home automation projects using the Raspberry Pi Zero board. The book will teach you how to build a thermostat that will automatically regulate the temperature in your home. Another important topic in home automation is controlling electrical appliances, and you will learn how to control LED Lights, lamps, and other electrical applications. Moving on, we will build a smart energy meter that can measure the power of the appliance, and you’ll learn how to switch it on and off. You’ll also see how to build simple security system, composed of alarms, a security camera, and motion detectors. At the end, you will integrate everything what you learned so far into a more complex project to automate the key aspects of your home. By the end, you will have deepened your knowledge of the Raspberry Pi Zero, and will know how to build autonomous home automation projects.

Control a LED from anywhere in the world


For the first project of this chapter, we are simply going to learn how to control a simple LED from a cloud dashboard.

For this project, you will need a LED and a 330 Ohm resistor. For the connection of the components to the Pi, you can refer to Chapter 4, Control Appliances from the Raspberry Pi Zero of this book, in which you will learn how to connect those components. You need to connect the LED to GPIO14 of the Pi.

This is the final result:

Let's now see how to configure the board, so we can control it from the cloud. To do so, we'll use the aREST framework that we have already used several times in this book. The following is the complete code for this part:

// Required modules
var express = require('express');
var app = express();
var piREST = require('pi-arest')(app);

// Thing name
piREST.set_id('98t52d');
piREST.set_name('pi_zero_cloud');
piREST.set_mode('bcm');

// Connect to cloud.aREST.io
piREST.connect();

// Start server
var server = app...
