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.

String library

The String library, which is part of the Arduino core libraries, enables us to use and manipulate text easier and in a more complex way then character arrays do. It does take more memory to use the String library than it does to use character arrays but it is easier to use the String library

There are numerous ways to create an instance of the String type. Let's look at a few examples here:

String str1 = "Arduino";
String str2 = String("Arduino");
String str3 = String('B');
String str4 = String(str2 + " is Cool");

Both of the first two lines create a simple string with the word Arduino in it. In the third line, a new String instance is created from a single constant character. In this line, notice that the single quote is used. The last example concatenates two Strings. There are several more constructors that enable...
