ESP32 is a low-cost MCU with integrated Wi-Fi and BLE. Various modules and development boards-based ESP32 are available to build Internet-of-Things ( IoT ) applications easily. Wi-Fi and BLE are common network stacks in IoT applications. These network modules can fulfil your business and project needs, providing cost-effective benefits.

This book will serve as a fundamental guide to developing an ESP32 program. We will start with GPIO programming, which will involve some sensor devices. Then, we will get deep into ESP32 development by building some IoT projects such as a weather station, a sensor logger, a smart home device, a Wi-Fi camera, and Wi-Fi Wardriving. Lastly, we will enable ESP32 to interact with mobile applications and cloud servers such as Amazon AWS.

By the end of this book, you will be up and running with various IoT projects based on the ESP32 chip .

This book is designed for students, professional designers, developers, and IoT enthusiasts. Basic knowledge of ESP32 is not required to work with the content of this book.

, Getting Started with ESP32, presents a review of the ESP32 board. We also set up a development environment for ESP32 boards.

, Making Visual Data and Animation on an LCD, offers a brief introduction to weather systems. Here, we'll make a simple ESP32 program to sense temperature and humidity using the DHT22 sensor module. Furthermore, we'll work with the LCD on the ESP32 board, accessing the LCD modules through the ESP32 board.

, Building a Simple Game with an Embedded ESP32 Board, teaches you how to work with an analog joystick, along with an exploration of a simple sound device with a sound buzzer, and the development of a simple game.

, Building a Sensor Monitoring Logger, covers how to work with external storage, such as SD cards and microSD cards, on an ESP32 board. We'll store our sensor data on external storage, and use a sensor monitoring logger by applying sleep mode after sensing and storing sensor data.

, Controlling IoT Devices over the Internet
