Overview of this book

ESP32 is a versatile microcontroller and a great starting point for anyone venturing into the IoT realm, but its configuration and interfacing of sensors can be challenging for new users. Arduino Integrated Development Environment (IDE) simplifies programming, uploading code, and utilization of ESP32 capabilities, enabling users to incorporate it into their IoT projects with ease. This book will help you learn the essentials of sensing, networking, data processing, and applications with ESP32, laying a strong foundation for further IoT development. Starting with ESP32 and Arduino Ide 2.0 basics, you'll first explore practical implementation examples of interfacing sensors with ESP32. These examples will also teach you how to interface the ESP32 camera and display modules with ESP32. As you progress, you’ll get to grips with IoT network and data protocols, as well as the many options they unlock within IoT applications. The book will also help you leverage your newly acquired knowledge with exciting projects ranging from smart connected devices to data loggers and automation. By the end of this book, you'll confidently navigate ESP32 projects with newfound knowledge and skills, know what IoT protocol to select for your applications, and successfully build and deploy your own IoT projects.

Connecting Sensors and Actuators with ESP32

In this chapter, we will dive into the world of sensors and actuators with the ESP32, a highly versatile and powerful microcontroller. By exploring its built-in features and connectivity options, you will develop a fundamental understanding of how to interact with the physical world using advanced pieces of hardware.

We will start with the introduction to the ESP32’s general purpose input/output (GPIO) pins and their functionality. Next, we will learn about universal asynchronous receiver-transmitters (UART) and serial communication, which will enable us to exchange data between devices. After mastering UART, we will turn our attention to the serial peripheral interface (SPI) communication protocol, a method commonly used to send data between microcontrollers and small peripherals. Finally, we will delve into I2C communication, a highly efficient two-wire protocol used for short-distance data transmission.
