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:

With the diagram, we can see that the ground pin on the HC-SR501 motion sensor is connected to the ground rail on the breadboard and the 5V input on the motion sensor is connected to the power rail on the breadboard. The power and ground rails of the breadboard are connected to the 5V power and ground pins on the Arduino.

The output pin on the motion sensor is a digital output (either HIGH or LOW), therefore we can connect the output pin directly to any of the digital pins on the Arduino. In this case, we are connecting the output pin from the sensor to pin three on the Arduino.

Here is the schematic diagram of the same circuit:

Let's look at the Arduino code for this project.
