Developing IoT Projects with ESP32

By: Vedat Ozan Oner

Overview of this book

Developing IoT Projects with ESP32 provides end-to-end coverage of secure data communication techniques from sensors to cloud platforms that will help you to develop production-grade IoT solutions by using the ESP32 SoC. You'll learn how to employ ESP32 in your IoT projects by interfacing with different sensors and actuators using different types of serial protocols. This book will show you how some projects require immediate output for end-users, and cover different display technologies as well as examples of driving different types of displays. The book features a dedicated chapter on cybersecurity packed with hands-on examples. As you progress, you'll get to grips with BLE technologies and BLE mesh networking and work on a complete smart home project where all nodes communicate over a BLE mesh. Later chapters will show you how IoT requires cloud connectivity most of the time and remote access to smart devices. You'll also see how cloud platforms and third-party integrations enable endless possibilities for your end-users, such as insights with big data analytics and predictive maintenance to minimize costs. By the end of this book, you'll have developed the skills you need to start using ESP32 in your next wireless IoT project and meet the project's requirements by building effective, efficient, and secure solutions.

Summary

In this chapter, we have seen many sensors and actuators that we can use in real-world projects. Starting from a simple button and LED driving, we have reached a point where we can use stepper motors to design our very own 3D printers. Although the main focus was sensors and actuators, we have also learned how to use peripherals such as GPIO pins, ADC, and PWM, and different communication protocols such as 1-Wire or I2C, which you can apply anytime you need to use a different sensor or actuator not listed in this book. Some useful FreeRTOS functions have also been added to our knowledge base to be employed in our projects.

The next chapter is about more advanced features of ESP32. We are going to test different types of displays and discuss their features. We will continue to use different peripherals such as Inter-IC Sound (I2S) and a universal asynchronous receiver-transmitter (UART) for different purposes. One interesting feature of ESP32 is its ultra-low power (ULP)...
