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.

Exploring HTTP with ESP32 – enabling IoT devices to communicate with web servers

In the interconnected world of IoT, efficient communication between devices and web servers is paramount. One of the foundational protocols that has powered the internet since its beginning is HTTP. In the context of IoT, HTTP plays a pivotal role in facilitating communication between resource-constrained devices, such as the ESP32 microcontroller, and remote web servers. This section dives into the details of HTTP communication, specifically tailored for ESP32 projects. We’ll explore how ESP32 can seamlessly interact with web servers, enabling IoT devices to exchange data, retrieve information, and contribute to the ever-expanding landscape of IoT. First, let’s explore what the HTTP protocol is and how it works.

What is HTTP?

HTTP is the foundation of data communication on the World Wide Web. It is an application layer protocol that defines how clients (typically web browsers...
