This book will serve as a fundamental guide for developing an ESP32 program. We will start with GPIO programming involving some sensor devices. Then we will study ESP32 development by building a number of IoT projects, such as weather stations, sensor loggers, smart homes, Wi-Fi cams and Wi-Fi wardriving. Lastly, we will enable ESP32 boards to execute interactions with mobile applications and cloud servers such as AWS. By the end of this book, you will be up and running with various IoT project-based ESP32 chip.

It is estimated that trillions of devices will be interconnected over the next decade through the Internet of Things, demanding a huge effort from developers. The emergence of cheap Espressif microcontrollers, featuring WiFi connectivity, allows independent developers to quickly become part of this process.

This book is not intended to comprehensively teach you the theory, but to give you practical and fully functional solutions, in the form of complete programs.

The content of this material describes the different stages in the realization of a functional project used as an example. The project is entitled: LED V1.0 Basically, it consists of being able to control the on / off and power in a LED power device in two ways, both via the Internet through a virtual dashboard or "Dashboard" in Adafruit, and locally using a smartphone (Wi-Fi access).
