Chapter 1, Connecting an Arduino to the Web, focuses on getting you started by connecting an Arduino board to the Web. It will lay foundation for the rest of the book.

Chapter 2, Cloud Data Monitoring, deals with one of the most important thing you can do with an Internet of Things project, that is, send data online so that it can be stored, retrieved later, and plotted inside a nice dashboard.

Chapter 3, Interacting with Web Services, tells us how to use existing web services to build amazing Internet of Things projects with our Arduino board.

Chapter 4, Machine-to-Machine Interactions, focuses on something different: making two (or more) Arduino boards talk to each other and interact with each other, without any human intervention. This is known as machine-to-machine communications, which is a very exciting field of the IoT. Let's dive in!

Chapter 5, Home Automation Projects, tells us how to apply what we learned so far in this book to the home automation field. We are going to use the Arduino board to build several home automation projects that will be accessible from anywhere in the world & able to communicate with cloud services.

Chapter 6, Fun Internet of Things Projects, deals with how to build a clock that gets the time from the cloud, but also an actual GPS tracker that will display the position of your Arduino project on Google Maps!

Chapter 7, Mobile Robot Applications, tells us how to create our own mobile robot based on Arduino. Finally, to end this book about the Internet of Things, we are going to learn how to control this robot from anywhere in the world.

All the projects of this chapter and this book are using Arduino MKR1000 board. This is an Arduino board released in 2016 that has an on-board WiFi connection. You can make all the projects of the book with other Arduino boards, but you might have to change part of the code

This book is primarily for tech enthusiasts and early IoT adopters who would like to make the most of IoT and address the challenges encountered while developing IoT-based applications with Arduino. This book is also good for developers with basic electronics knowledge who need help to build successful Arduino projects.

In this book, you will find several headings that appear frequently (Getting ready, How to do it, How it works, There's more, and See also).

To give clear instructions on how to complete a recipe, we use these sections as follows:

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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

if (millis() - lastConnectionTime > postingInterval) {

    // Measure light level
    int sensorData = analogRead(A0);

    // Send request
    httpRequest(sensorData);
  }

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

# cp /usr/src/asterisk-addons/configs/cdr_mysql.conf.sample
     /etc/asterisk/cdr_mysql.conf

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 do that, open the Arduino boards manager by going to Tools | Boards | Boards Manager."
