ESP32 Embedded Systems: From GPIO and Sensors to Wi-Fi, Bluetooth, FreeRTOS, IoT, TinyML, and Production-Ready Devices

By David Matthew

Turn a $4 microcontroller into a fully networked, intelligent device - no prior embedded experience required.

ESP32 Embedded Systems: A Complete Guide takes you from your very first blinking LED to building production-grade IoT systems with real-time multitasking, edge AI, and hardened security. Written for makers, students, and engineers alike, this book skips the theory-heavy padding and gets straight into hands-on projects you can build on real hardware.

Inside, you'll learn how to:

Master GPIO, analog input, and sensor interfacing over I2C, SPI, and UARTHarness interrupts, hardware timers, and FreeRTOS to build responsive, multi-tasked firmwareConnect your ESP32 to Wi-Fi, REST APIs, and MQTT brokers for real-world IoT communicationAdd Bluetooth Low Energy for smartphone-connected devices - no internet requiredControl motors and build an autonomous, obstacle-avoiding robotExtend battery life for months using deep sleep and solar/battery power managementRun TinyML models directly on the ESP32 for on-device gesture and anomaly detectionLock down your devices with TLS, authentication, and watchdog-based fault recoveryArchitect a complete smart-hub system that ties sensing, actuation, and remote monitoring together

Each chapter builds toward a hands-on close-out project, and eight reference appendices - covering hardware pinouts, C/C++, FreeRTOS, IoT protocols, and troubleshooting - make this a book you'll keep on your desk long after you've finished reading it.

Whether you're prototyping your first IoT gadget or leveling up from Arduino to production-ready embedded engineering, this is the field guide the ESP32 deserves.
