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.

Comparison operators

The Arduino programming language includes comparison operators that enable us to compare the values of two operands. The comparison operators return a Boolean value indicating if the comparison was true or false. The following code shows how we would use these operators:

x == y // returns true if x is equal to y
x != y // returns true if x is not equal to y
x > y // returns true if x is greater than y
x < y // returns true if x is less than y
x >= y // returns true if x is greater or equal to y
x <= y // returns true if x is less than or equal to y

Now that we have seen the comparison operators that the Arduino programming language provides, let's look at the logical operators.
