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.

Code

Before we can start writing code, we will need to load in the DHT11 Adafruit library that we will be using to read the temperature and humidity readings. You can find the source code for this library on Adafruit's GitHub page here: https://github.com/adafruit/DHT-sensor-library.

Note: You will need to refer to this code for the challenge section of this chapter.

To install the library, if you are using the Arduino IDE, select the Sketch option in the menu bar and select Include Library and then Manage Libraries as shown in the following screenshot:

In the window that opens up, type dht11 in the search bar and you should see a couple different DHT11 sensor libraries. In this chapter, we will be using the one from Adafruit (In the following list, the first result). Click on this library, and you will see a button all the way to the right to install it as shown in the...
