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

A DC motor is a class of rotary electrical device that converts electrical energy into physical motion. There are numerous types of DC motors; however, in this chapter, we will look at one specific type, which is the brushed DC motor.

Brushed DC motors are used in a wide variety of applications, ranging from toys and robotics to powered windows and power tools. Some advantages of brushed DC motors are their initial low cost, simple control, and low-speed torque. The disadvantages of these motors are their high maintenance costs and low lifespan in high-intensity environments. For the prototyping and robotic projects that we normally do with the Arduino, the disadvantages of the brushed DC motors are normally not a concern.

At the center of a brushed DC motor is a spinning armature, which contains an electromagnet. To the outside of the spinning armature is a...
