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.

A real-life analogy of HTTP, MQTT, and webhooks

Imagine you’re hosting a big party at your house. The party invitations are like HTTP requests. You send out invitations (requests) to your friends, telling them about the party details and asking them to reply. When your friends arrive at the party, they bring gifts (data) and hand them over to you, just like how a web server receives and processes HTTP requests.

Now, let’s add webhooks to the mix. Think of webhooks as a special guest list you have. You’ve asked your friends to not only come to the party but also let you know when they’re on their way so that you can be prepared. With webhooks, your friends send you messages whenever they’re leaving their homes (events happening in their systems). This way, you can get ready to welcome them and ensure everything is in place when they arrive.

Lastly, imagine your party has a live band that plays music for everyone to enjoy. This band represents...
