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.

Making things rotate

In Chapter 16, Servo Motors, we saw how we could use a servo motor to open and close a robotic claw; however, a servo motor can do so much more than that. With a servo motor, as we saw with the robotic claw, we can rotate the motor to a specific angle. In the past, I have attached a MaxSonar Range Finder to a servo motor and pointed the sensor straight ahead. Then when the rangefinder detected an object in front of the robot, the servo would turn the rangefinder in different directions, so it could determine the best direction to move in. This enabled me to build an autonomous robot, with obstacle avoidance, using only a single rangefinder.

We could also attach a light source to a servo motor to make a rotating searchlight that will enable you to see where the robot is in the dark, or equally it is just a really cool addition to your robot with really no functional...
