Preface

As technology is evolving, things that surround us in our daily lives are starting to have the ability to share data over the Internet. With this evolution, it is no longer the case that only humans can operate the devices connected to the Internet. These devices are now able to collect and share sensorial data that can be controlled by sensor inputs. They also help you power up big data analysis, monitor systems, and even make devices work together for a common purpose. A new era has begun, the era of Internet of Things!

Following this vision, Intel presented the Galileo board, a board that packs together many of the most common components that are usually purchased separately for most development boards. An Intel Galileo Board can be programmed to read and control sensors and actuators, being an interesting tool for sensorial data collection. The possibility of connecting it straight to the Internet using an Ethernet cable or a wireless card in its mini PCI-express slot enables it to share the collected data over the Internet. Another great feature is that being hardware and software compatible with Arduino, it will make you have a very familiar development environment. If you prefer using other development tools, you can also do that by booting your board from a custom Linux image.

This book will give you the right tools to help you start developing your own IoT projects using an Intel Galileo board.

What this book covers

Chapter 1, Introducing Galileo, introduces you to the Intel Galileo boards by explaining their components, main differences when compared to other boards, and the other interesting boards for building IoT projects.

Chapter 2, Rediscovering the Arduino IDE, will guide you through the Arduino IDE from the process of setting up your board to uploading and running your first sketches.

Chapter 3, Monitoring the Board Temperature, will help you develop your first IoT project with the Arduino IDE. You'll create and collect temperature data samples from your own board CPU temperature and plot it to an online chart using Galileo as a web client.

Chapter 4, Creating a Motion Sensing Light, will show you how to create a web server with the Arduino IDE and use it to display a web page, allowing you to switch the lighting system operation mode, which is controlled by motion sensor, either by luminosity or manually.

Chapter 5, Intel IoT Developer Kit Tools, introduces you to the Intel ecosystem, giving you an overview of its perks and how you can use its main libraries to read and control your sensors and actuators in other development languages.

Chapter 6, Building an Irrigation System, will guide you through the process of monitoring your sensor data using Wyliodrin, and the creation of rules to control actuators.

Chapter 7, Creating Christmas Light Effects, will teach you how to create remotely controlled animations using an LED strip and a YouTube player.

Chapter 8, The Intel XDK IoT Edition, will explain how you can use the Intel XDK IoT Edition IDE to develop Node.js projects for Galileo.

Chapter 9, Developing an IoT Quiz, will help you develop a quiz game played with mobile devices.

Chapter 10, Integrating with Muzzley, will show you how you can integrate Galileo in your daily life. You'll be creating a building door unlocking system using your Galileo board and integrating it with market-available smart devices using the Muzzley cloud-based ecosystem.

Who this book is for

This book is intended for developers, hobbyists, and enthusiasts in general. Basic background knowledge of computing, electronics, and microcontroller development with technology such as Arduino or Raspberry Pi boards will make the learning process easier. Also, an awareness of the basic development concepts of Arduino and Node.js (JavaScript) will be helpful.

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "In the demos you tested in the previous steps, you've tried only the digitalWrite and analogWrite methods."

A block of code is set as follows:

socket.on('error', function (error) {
  console.log('Something went wrong!');
});

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

exports = module.exports = {};
exports.start = runAnimation;
exports.stop = stopAnimation;

Any command-line input or output is written as follows:

npm install async

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: " To see all the available libraries, navigate to Sketch | Import Library... on the IDE top menu."

Note

Warnings or important notes appear in a box like this.
