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.

Mastering UART communication

A UART is a hardware device or a protocol that manages asynchronous serial communication between devices. It facilitates data transmission by converting bytes of data from the CPU into a continuous stream of bits suitable for transfer via communication links. One of the key features of UART is that it does not require a clock signal. This simplifies hardware, reduces power consumption, and allows flexible data rates but may also lead to potential timing and synchronization issues between the sender and receiver, requiring additional overhead for start and stop bits and making it less suitable for high-speed or long-distance communication. The absence of a clock signal makes this protocol asynchronous. This simple yet powerful communication protocol is commonly used in microcontroller-based projects for inter-device communication, making it an essential part of our ESP32 study.

In this section, we will cover the following topics related to UART in the...
