Learning Embedded Systems with STM32 Nucleo Boards Programming compact electronic systems is now easier to get started with than ever before. Affordable development boards, powerful software tools, and readily available documentation make it possible to turn an idea into a working prototype in very little time. MicroPython plays an important role in this development by offering a readable, interactive way to control microcontrollers while still providing direct access to their hardware features. This book explores embedded programming with MicroPython using an STM32-based Nucleo board. It shows how a microcontroller continuously interacts with its environment by reading inputs, processing information, and controlling outputs. Step by step, you will learn to flash LEDs, measure analog signals, work with sensors, control actuators, and exchange data with other devices. The built-in REPL makes it easy to test instructions immediately, inspect results, and learn through experimentation. Although microcontroller boards differ in size, speed, memory, and peripherals, the fundamental concepts remain largely the same. Digital input and output, analog conversion, timers, PWM, interrupts, and serial communication are the essential building blocks of embedded applications. By concentrating on these transferable principles, the book provides a foundation that remains useful when moving to other boards, processors, or development environments. It is intended both for newcomers and for programmers who want to expand into embedded systems. MicroPython offers a practical route into this field, combining quick results with a clear understanding of how software and hardware work together.

Learning Embedded Systems with STM32 Nucleo Boards Embedded programming has become more accessible than ever before. Development boards are inexpensive, software tools are easy to install, and the Arduino IDE provides a familiar environment for creating embedded applications. Combined with the STM32 Nucleo family of development boards, it offers an excellent platform for learning how modern microcontrollers interact with the physical world. This book introduces embedded programming using the Arduino environment on STM32 Nucleo boards. You will learn how a microcontroller continuously reads inputs, processes information, and controls outputs in a predictable real-time loop. Through practical examples, you will discover how to control LEDs, read switches and sensors, generate PWM signals, drive motors, and exchange data with other devices, all while becoming familiar with the capabilities of STM32 microcontrollers. Although the STM32 family includes devices with different performance levels, memory sizes, and peripheral sets, they all share the same architectural concepts. Digital and analog I/O, timers, interrupts, PWM, communication interfaces, and low-power operation are fundamental features found throughout the STM32 ecosystem. Understanding these building blocks will enable you to work confidently with a wide range of STM32 devices, from entry-level microcontrollers to more advanced applications. By focusing on practical programming techniques rather than hardware complexity, this book develops skills that remain useful well beyond the examples presented. Whether you are taking your first steps in embedded systems or expanding your experience with STM32 microcontrollers, you will gain a solid understanding of both the Arduino development environment and the principles that underpin embedded software design.

If you can describe it, you can build it AI coding assistants are changing what makers and solopreneurs can build. Tasks that once demanded weeks of learning a new language, framework, or software stack can now be delegated to an AI—provided you know how to describe the job, judge the result, and keep control of the process. The Maker’s Guide to AI Coding is a practical guide to doing exactly that. It explains how to work with AI coding tools as collaborators rather than vending machines, how much to delegate, how to write specifications that produce useful results, and how to recognise hallucinations, context drift, overconfidence, and code that runs but is still wrong. The book is built around four increasingly ambitious projects. You begin with a browser-based RC filter analyser, then develop a live serial data plotter for Arduino and other microcontrollers. Next comes a datasheet questionand- answer tool using retrieval-augmented generation (RAG), followed by a complete multi-user resource booking system with authentication, a database, external services, background jobs, and deployment. No advanced programming background is required. The emphasis is on thinking clearly, guiding the AI, testing what it produces, and preserving the skills needed to evaluate its work. Along the way, you learn development workflow designed to remain useful as tools evolve. If you can describe what you want to build, this book shows you how to turn that description into working software.

The story of the engineers who shaped the world's most powerful chip machines How do you transform a hopeless research and business activity into a billion-dollar machine and a world-leading company? The Dutch enterprise ASML pulled it off, and the book ASML’s Architects by renowned technology writer René Raaijmakers reveals exactly how. ASML's Architects travels back to the origins, struggles, success factors and sheer luck of a company that was barely alive at the beginning of the 80s, yet managed to become the uncontested world leader in chip lithography. Today, ASML determines the pace at which all information technology advances. The book covers the technology and the business, but the real story is in the people behind them. Throughout its pages, the interviewed engineers, scientists and managers speak frankly about their struggles, their fights and the grueling teamwork behind the scenes.

This hands-on bundle lets you build real Edge AI applications with the Raspberry Pi Raspberry Pi AI HAT+ (13 TOPS) The Raspberry Pi AI HAT+ (13 TOPS) is an expansion board designed for the Raspberry Pi 5, featuring an integrated Hailo AI accelerator. This add-on offers a cost-effective, efficient, and accessible approach to incorporating high-performance AI capabilities, with applications spanning process control, security, home automation, and robotics. The AI HAT+ connects via the Raspberry Pi 5’s PCIe Gen3 interface. When the Raspberry Pi 5 is running a current version of the Raspberry Pi OS, it automatically detects the onboard Hailo accelerator, making the neural processing unit (NPU) available for AI tasks. Additionally, the rpicam-apps camera applications included in Raspberry Pi OS seamlessly support the AI module, automatically using the NPU for compatible post-processing functions. Raspberry Pi Camera Module 3 Raspberry Pi Camera Module 3 is a compact camera from Raspberry Pi. It offers an IMX708 12-megapixel sensor with HDR, and features phase detection autofocus. Camera Module 3 is available in standard and wide-angle variants, both of which are available with or without an infrared cut filter. Camera Module 3 can be used to take full HD video as well as stills photographs, and features an HDR mode up to 3 megapixels. Its operation is fully supported by the libcamera library, including Camera Module 3’s rapid autofocus feature: this makes it easy for beginners to use, while offering plenty for advanced users. Camera Module 3 is compatible with all Raspberry Pi computers. Book: Edge AI Made Practical – AI Projects for the Raspberry Pi with the AI HAT+ Edge AI is transforming everyday devices by putting intelligence where it matters most: directly inside the hardware. With on-device inference, a camera can recognize a visitor instantly, a phone can translate speech without streaming audio to the cloud, and a wearable can detect anomalies in real time—fast, private, and reliable even when the network disappears. This book is your practical guide to building exactly those kinds of systems with the Raspberry Pi AI HAT+ and the Hailo-8L accelerator. You’ll start with clear foundations: core AI and machine-learning concepts, how neural networks work, and what truly distinguishes Edge AI from cloud AI—plus an honest look at ethical considerations and future impacts.
