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.

Interfacing sensors with ESP32

In this section, we will dive into the hardware of our parking space rental project. Here, we will explore the integration of a diverse array of sensors and actuators with the ESP32 microcontroller, enabling us to enhance the functionality and user experience of our prototype.

Our project relies on the seamless coordination of various components to monitor parking space availability, handle secure payments through the PayPal API, and ensure a user-friendly experience. To achieve this, we will connect the ESP32 with essential components, including an ultrasonic sensor, an SSD1306 OLED I2C display, a Servo motor, an RGB LED, and a push button.

The ultrasonic sensor enables precise measurement of distances, a crucial aspect of monitoring parking spaces. The SSD1306 OLED I2C display provides visual feedback to users, displaying relevant information about parking availability and transactions. The Servo motor gives us the ability to control physical...
