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.

Getting hands-on with ESP32 GPIO pins and an overview of them

GPIO is a fundamental feature found in microcontrollers and other embedded systems. It refers to the ability of the microcontroller to interact with the external world by providing a flexible set of input and output pins. GPIO pins can be configured to either read or write digital signals, allowing the microcontroller to communicate with various devices and peripherals. As input, GPIO pins can detect the state of external sensors, switches, or digital signals. For example, we can read the temperature from temperature sensors. As outputs, they can drive LEDs, control motors, or interface with other electronic components. The versatility of GPIO pins makes them essential for a wide range of applications, enabling the microcontrollers to interact with and control the physical environment.

In this section, we will dive into ESP32 GPIO pins and explore their potential. By understanding this topic, you will be able to control...
