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.

I2C communication with ESP32

I2C is another serial communication protocol, but unlike the UART protocol, it is a synchronous communication protocol that is used for communications between integrated circuits or devices on a shared bus. Since it is a synchronous communication protocol, it requires a clock signal and works in the master-slave architecture. Therefore, it is commonly used in scenarios where multiple devices need to communicate with the master/central device.

In this section, we will explore the following topics related to I2C communication in the context of ESP32 and Arduino IDE:

  • How I2C communication works
  • I2C communication example using ESP32
  • Sensors that use I2C communication

By the end of this section, you will be able to explain the I2C protocol, differentiate it from UART, use it with ESP32 using Arduino IDE, and understand some of the common sensors available on the market that can be interfaced using I2C.
