Overview of this book

Mastering Arduino is an all-in-one guide to getting the most out of your Arduino. This practical, no-nonsense guide teaches you all of the electronics and programming skills that you need to create advanced Arduino projects. This book is packed full of real-world projects for you to practice on, bringing all of the knowledge in the book together and giving you the skills to build your own robot from the examples in this book. The final two chapters discuss wireless technologies and how they can be used in your projects. The book begins with the basics of electronics, making sure that you understand components, circuits, and prototyping before moving on. It then performs the same function for code, getting you into the Arduino IDE and showing you how to connect the Arduino to a computer and run simple projects on your Arduino. Once the basics are out of the way, the next 10 chapters of the book focus on small projects centered around particular components, such as LCD displays, stepper motors, or voice synthesizers. Each of these chapters will get you familiar with the technology involved, how to build with it, how to program it, and how it can be used in your own projects.

Data types

There are numerous, built-in, data types in the Arduino programming language. In this section, we will look at the most commonly used ones. Let's begin by looking at the Boolean type.

Boolean

The Boolean data type can contain one of two possible values, true or false. The following example shows how to declare a variable to be of the Boolean type:

boolean myBool = true;

The preceding code declares a variable named myBool of the Boolean type and sets an initial value of true. Boolean types are used a lot within a standard Arduino program and all comparison operations, as we will see later in this chapter, return a Boolean value.
