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.

Circuit diagrams

The following diagram shows the Fritzing diagram for this project:

The middle sensor, shown in the diagram, represents the crash sensor because there isn't a Fritzing part for a crash sensor. The switch in the diagram has the same pin layout as the crash sensor shown earlier in this chapter.

In the diagram, we can see that all of the ground pins on the sensors are connected to the ground rail of the breadboard and all of the VCC pins on the sensors are connected to the power rail on the breadboard.

The analog out on the EZ1 Ultrasonic sonar sensor is connected to the A1 analog pin on the Arduino, the crash sensor is connected to digital pin 3 and the infrared sensor is connected to digital pin 2. The crash sensor also has a 4.7K pull-up resistor. Now that we have the sensors connected to the Arduino, let's look at the code for this project.
