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.

Architecture, Programming and Applications The MSP430 is a popular family of microcontrollers from Texas Instruments. In this book we will work with the smallest type, which is the powerful MSP430G2553. We will look at the capabilities of this microcontroller in detail, as it is well-suited for self-made projects because it is available in a P-DIP20 package. We will take a closer look at the microcontroller and then build, step by step, some interesting applications, including a 'Hello World' blinking LED and a nice clock application, which can calculate the day of the week based on the date. You also will learn how to create code for the MSP microcontroller in assembler. In addition to that, we will work with the MSP-Arduino IDE, which makes it quite easy to create fast applications without special in-depth knowledge of the microcontrollers. All the code used in the book is available for download from the Elektor website.

PIC und AVR verstehen In diesem Buch werden wir uns ausschließlich mit 8-Bit-Mikrocontrollern beschäftigen, und zwar mit Mikrocontrollern der 8-Bit-PIC- und der 8-Bit-AVR-Mikrocontroller-Linien. Bei der PIC-Familie handelt es sich dabei um PIC10, PIC12, PIC16 und PIC18; bei der AVR-Familie um ATtiny, ATmega und ATxmega. Die vorgestellten 8-Bit-Chips sind für sehr viele Anwendungen vollkommen ausreichend und preislich auch attraktiv. Durch die Lektüre des Buches erhalten Sie ein fundiertes Wissen über die genannten 8-Bit-Mikrocontroller, über ihre Architektur, ihre Pinbelegungen und über ihre Programmierung. Weil wir uns in diesem Buch mit den Grundlagen der Architektur der PICs und AVRs vertraut machen möchten, werden wir auch für alle PIC- und AVR-Anwendungen Assembler einsetzen, denn die Assembler-Sprache erlaubt es, die Technik im Detail kennenzulernen. Wenn man wirklich wissen möchte, was sich im Mikrocontroller abspielt, greift man zu Assembler. Damit hat man die beste Gelegenheit, sehr nah an den Kern zu kommen. Und wenn man schon einen Mikrocontroller-Typ kennengelernt und verstanden hat, ist es bei dem nächsten deutlich einfacher, auch wenn er von einem anderen Hersteller kommt. Bei anderen Programmiersprachen bleibt die Technik immer ziemlich tief versteckt. Die Assembler-Beispiele sind so einfach gestaltet, dass sie jeder mit den im Buch aufgezeigten Programmiertechniken erstellen kann. Weil es sich um einfache Beispiele handelt, werden wir sie alle auf einer universellen Lochrasterplatine realisieren. Manche sind auch auf einem Experimentier-Breadboard umsetzbar.

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.

Wie enigszins bekend is met moderne microprocessor systemen als Arduino, kent ongetwijfeld ook de problemen met dit soort kaarten. Ze zijn te duur om voor elk project een aparte kaart aan te schaffen en zijn bovendien nogal fors van formaat. Het aardige van de ATtiny is dat de schijn bedriegt. Het lijkt een klein IC met een beperkt toepassingsgebied, maar het heeft een verbazingwekkend scala aan (speelse) mogelijkheden. Dit boek beschrijft de enorme veelzijdigheid van de ATtiny microcontroller aan de hand van ongeveer vijftig leuke elektronica projecten, speciaal gericht op de beginner.  De meeste ontwerpen zijn volledig uitgewerkt, enkele zijn meer als ontwerpidee gepresenteerd. De inhoudsopgave laat zien dat we ons op vele terreinen zullen begeven, van zonnevolger tot helling indicator. Dit boek is beslist geen theorieboek. Het is een boek dat gelezen zal worden met de soldeerbout in de hand. Voor het programmeren van de ATtiny maken we dankbaar gebruik van een Arduino kaart. Als de Arduino ingesteld word als programmer, kunnen we er de meeste Arduino “sketches” mee overzetten naar de ATtiny. We wensen u veel plezier met het nabouwen van de schakelingen.
