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:

In this diagram, we can see that the VCC and ground pins on both sensors are connected to the power and ground rails on the breadboard. The power and ground rails on the breadboard are connected to the 5V out and the ground pins on the Arduino.

The image of the DHT11 sensor that we showed earlier in this chapter shows a DHT11 sensor with three pins; however, the sensor in the Fritzing library has four pins. It is safe to ignore the extra pin on the Fritzing diagram.

This diagram shows that the data pin on the DHT11 sensor is connected to the digital 3 pin on the Arduino and it also has a 4.7K pull-up resistor. If the DHT11 sensor that you are using does not have a built-in pull-up resistor, you will need to add this external one that is shown in this diagram. The analog out on the rain sensor...
