MicroPython Embedded Systems in Practice: Microcontrollers, Automation, and Connected Devices: Build Practical Applications with GPIO, Sensors, I2C, SPI, UART, IoT, Networking, Real-World Hardware

Embedded development no longer has to begin with complex toolchains and thousands of lines of low-level code. MicroPython Embedded Systems shows how the accessibility of Python can be combined with microcontroller hardware to build practical connected devices, automation solutions, sensor systems, and Internet of Things applications.
Written for programmers, makers, engineering students, electronics enthusiasts, IoT developers, and newcomers to microcontrollers, this book provides a practical path from basic embedded concepts to increasingly capable hardware projects.
Readers first develop an understanding of the environment in which MicroPython operates: microcontrollers, memory, processors, digital and analog signals, pins, peripherals, communication buses, timing, and hardware constraints. From there, the book demonstrates how Python code can interact directly with physical electronics.
Core topics include GPIO, digital input and output, PWM, ADC, timers, interrupts, sensors, actuators, displays, buttons, LEDs, relays, motors, and other common embedded components.
Readers then progress into essential hardware communication technologies including I2C, SPI, and UART, learning why each interface exists, how devices communicate across them, and how to integrate external modules into practical applications.
Networking and connected-device development form another major part of the book. Readers explore Wi-Fi connectivity, network communication, data exchange, web-based control, IoT concepts, automation, and methods for connecting embedded hardware with larger software systems.
The book also addresses the realities of writing Python for constrained hardware. Topics such as memory management, efficient program structure, timing, reliability, error handling, asynchronous operations, power considerations, debugging, and maintaining responsive applications help bridge the gap between experimental scripts and dependable embedded solutions.
Practical projects reinforce the concepts throughout the book. Instead of learning individual commands without context, readers see how sensors, communication protocols, control logic, networking, and physical devices can work together as complete systems.
Examples are structured to develop reusable engineering skills that can be transferred across supported MicroPython hardware rather than limiting the reader to a single project idea.
Whether you come from Python programming, electronics, IoT, automation, robotics, or traditional embedded development, MicroPython Embedded Systems provides a hands-on foundation for creating software that interacts with the physical world.
It is a practical guide to moving from Python code on a screen to intelligent applications running directly on microcontroller hardware.
