Hands-on ESP32 with Arduino IDE

Connected-device projects bring together code, sensors, communications, and real-world hardware. Hands-on ESP32 with Arduino IDE takes readers through those pieces with the ESP32 and Arduino IDE 2.0, moving from board setup and programming basics to practical ways of connecting components and exchanging data.

Start with the ESP32 and Arduino IDE

The opening chapters introduce IoT concepts, ESP32 boards and capabilities, and the Arduino IDE 2.0 workflow. Readers get a foundation for setting up the development environment and programming the board before moving on to more involved integrations.

Connect sensors, cameras, and displays

Practical examples cover GPIO, PWM, and common communication interfaces such as UART, I2C, and SPI. The book also explores working with ESP32 camera modules and a range of displays, including LCD, OLED, TFT, and e-paper. These topics help explain how the microcontroller can communicate with the components that give an IoT device its inputs and outputs.

Choose how devices communicate

Networking and data protocols are another major part of the guide. Topics include Wi-Fi, Bluetooth Low Energy, cellular connectivity, and LoRaWAN, alongside HTTP, MQTT, and webhooks. Comparisons between protocols give readers context for considering different communication approaches in their projects.

Put the pieces to work in projects

The practical section applies ESP32 and IoT concepts to project scenarios, including a smart plant-monitoring system. Its contents include sensor connections and data readings, plus sending updates through email, WhatsApp, Telegram, and Twitter/X-related services.

A practical route into IoT development

With its progression from setup and interfaces to protocols and project examples, this book is relevant to readers building familiarity with ESP32, Arduino IDE, and connected-device development. It offers a hands-on way to study how hardware connections and communication choices fit together in IoT work.
