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

You should already have the DHT-11 library downloaded from the example in Chapter 9, Environment Sensors, but you will need to download the MOVI library. If you go to the library manager and do a search for Movi, you will find several libraries that match that term. Look for the MOVI Voice Dialog Shield library by Audeme LLC and download it.

We will begin the sketch by including both the MOVI and the DHT libraries. The following code shows how to include both:

#include <DHT.h>
#include <MOVIShield.h>

Next, we will define the DHT pin/type and create an instance of the DHT type as we did in Chapter 9, Environment Sensors:

#define DHT_PIN 3
#define DHT_TYPE DHT11
DHT dht(DHT_PIN, DHT_TYPE);

Now we will want to create an instance of the MOVI type as shown in the following line of code. The Boolean false value indicates that we do not want serial debugging turned...
