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.

Challenge

This challenge is going to be a little different than most. There isn't really a project to do; instead, it is a thinking challenge. The challenge is to think about how all three of these sensors work can work together to create an autonomous robot. To do this, think about how all three of the sensors work:

  1. Crash sensor: A digital sensor that is tripped when the sensor bumps into something
  2. Infrared sensor: A digital sensor that is tripped when something gets close
  3. Ultrasonic range finder: Analog sensor used to detect how far an object is from the sensor

Here are the answers:

The Ultrasonic range finders are the most expensive by far, so I usually use only two of these sensors facing out form the front of the robot. These are used to by the robot to navigate around obstacles. With the ability to tell how far something is from the front of the robot, we can give...
