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.

Proximity sensor

In Chapter 10, Obstacle Avoidance and Collision Detection, we saw how to use the MaxSonar rangefinder. If we attached the rangefinder to a servo motor, which we saw in Chapter 16, Servo Motors, we could create a proximity sensor that could rotate up to 180 degrees to monitor a large portion of a room. When the proximity first starts up, it would need to run through an initial cycle to map where the objects are, to begin with, and then monitor if anything changes after the initial run. If the proximity sensor does detect that something is closer than it should be, it could play an alarm through a speaker as described in Chapter 12, Fun with Sound.

These are just some of the projects that you can create with the Arduino. Now for your last challenge.
