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.

In this chapter, we explored different data-based protocols for IoT applications. We first explored the HTTP protocol and learned how we could use HTTP with ESP32 to communicate with web servers and use ESP32 as a web server or HTTP client.

Continuing our exploration, we learned about the MQTT protocol, highlighting its real-time capabilities through the pub/sub model. By learning how to implement MQTT clients on ESP32, we acquired the ability to build dynamic and responsive IoT applications. Additionally, we harnessed the power of webhooks, using them to trigger actions based on events, thereby enhancing interactivity and connectivity with external services. This chapter equipped us with the expertise to choose the right protocol for specific project requirements.

In the next chapters, we’ll use all the resources we have learned about in this chapter and previous chapters to work on some real-life practical projects using ESP32.
