Practical Guide to Microcontrollers: Learning Embedded Systems with ATtiny, ATmega, ESP32 and Beyond by Example

Real-World Projects Using Microcontrollers

Master the art of embedded systems — from hardware design to real-world IoT applications.

This comprehensive guide teaches you how to design, program, and deploy microcontroller-based systems using ATtiny, ATmega, ESP32, and similar architectures.
Combining theory with practical examples, this book walks you through each stage of embedded development — from circuit design and firmware creation to communication, optimization, and deployment.

Through detailed schematics, code listings, and illustrated projects, you’ll learn how microcontrollers interact with sensors, displays, and networks to create functional, intelligent systems that solve real problems.

Inside You’ll Learn

• How microcontrollers process, store, and communicate with the real world

• Digital and analog I/O, timers, interrupts, and PWM control

• PCB design and power management fundamentals

• Serial, I²C, and SPI communication explained through examples

• Wireless and IoT design using Wi-Fi, Bluetooth, and LoRa

• Firmware architecture, OTA updates, and debugging workflows

• Low-power system design and energy-harvesting techniques

• Real-world projects built step-by-step with complete code and visuals

Why This Book?

Unlike introductory tutorials, this guide combines architecture, design, programming, and application into a single structured learning path. Each concept is supported by diagrams, practical schematics, and project code that you can reproduce and adapt.

Whether you’re a student, maker, or professional engineer, this book provides the tools and confidence to design embedded systems that are efficient, reliable, and ready for production.
