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.

Parallel circuits

The following schematic diagram shows a parallel circuit:

The preceding diagram shows a parallel circuit where the current has multiple paths to the return. The current can either flow through the branch with the 220-ohm resistor, the branch with the 330-ohm resistor or both branches.

In this sample circuit, as with the series circuit, the load consists of two resistors with values of 330 ohms and 220 ohms, however, this time the resistors are connected in parallel rather than series. The properties of a parallel circuit are very different than the properties of a series circuit. Let's look at these properties.

Resistance

The total resistance of a parallel circuit will always be less than the total...
