Preface

The ESP32 is a great microcontroller for learning and creating Internet of Things (IoT) applications. It’s especially good for beginners in the IoT world. Setting up and connecting sensors to the ESP32 can be complicated, but the Arduino IDE makes it easier to write code, upload it to the ESP32, and use its features. This book is designed to help you understand the basics of using sensors, connecting to networks, processing data, and creating applications with the ESP32, giving you a solid foundation for IoT development.

Starting with the basics of the ESP32 and the Arduino IDE 2.0, you’ll learn how to connect sensors to the ESP32 through practical examples. Then, the book shows you how to use the ESP32 camera and display modules with examples. It also explains IoT networks and data protocols, providing you with different options for various IoT applications. Toward the end of the book, you’ll use your knowledge to work on exciting projects, from smart connected devices to data loggers and automation, experiencing real-world applications.

By the end of the book, you’ll be able to confidently work on ESP32 projects, choose the right IoT protocol for your application, and successfully create and deploy your own IoT projects.
