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.

Introduction

In this chapter, we will look at three sensors that we can use to add obstacle avoidance and/or collision detection to our projects. These sensors are:

  • Crash sensor: Used to detect a crash and also used as limit switches for 3D printers
  • Infrared obstacle avoidance sensor: Used for obstacle avoidance for robotics
  • Ultrasonic range finder: Used for obstacle avoidance for robotics and has many other commercial and military uses

Crash sensor

A crash sensor is basically a simple switch that has some sort of extender on it that gives it a large area to detect a crash. The following photograph show what a basic crash sensor would look like:

The crash sensor shown in the preceding photograph takes a simple mechanical...
