Modular and Scalable Control Systems Using Structured Text
This book offers a structured and practical approach to modern PLC development using object-oriented principles. It is a guide for engineers, programmers, and students seeking to harness the power of object-oriented programming (OOP) in the context of industrial automation with PLCs.
The content focuses on the CODESYS development environment and Structured Text (ST), both of which support modern programming techniques while maintaining compatibility with real-time automation requirements. Through step-by-step demos and instructional examples, it demonstrates how modular, reusable code can enhance development efficiency, simplify ongoing maintenance, and enable scalable and flexible control system architectures.
Key topics include:
Structured Text fundamentals: conditions, loops, arrays, and functions
Object-oriented concepts: classes, methods, and inheritance
Advanced techniques: polymorphism, interfaces, and access control
Modular design with reusable components and structured program flow
Implementation of finite state machines and scalable application design
Built around instructional demos and clear explanations, this book helps readers develop maintainable and modern control software in the CODESYS environment using proven programming techniques.
Een retro-rol met een neonziel
Dobbelstenen met leds zijn gebruikelijk, maar hun licht is koud. Dat geldt niet voor deze elektronische neon-dobbelsteen, die zijn waarde toont met de warme gloed van neonlampen. Hij is perfect om te spelen op koude, donkere winteravonden. De ogen van de dobbelsteen zijn neonlampen en de random number generator heeft zes neonlampen om aan te geven dat hij werkt.
Hoewel de dobbelsteen een ingebouwde 100 V-voeding heeft, is hij volkomen veilig. Zoals bij alle Elektor Classic-producten is ook bij de dobbelsteen het schema op de voorkant afgedrukt, terwijl een uitleg over de werking van de schakeling op de achterkant te vinden is.
De neonlamp-dobbelsteen wordt geleverd als een bouwpakket met eenvoudig te solderen doorlopende onderdelen. De voeding is een 9 V-batterij (niet meegeleverd).

Sound Secrets and Technology
What would today’s rock and pop music be without electric lead and bass guitars? These instruments have been setting the tone for more than sixty years. Their underlying sound is determined largely by their electrical components. But, how do they actually work? Almost no one is able to explain this to the true musician with no technical background. This book answers many questions simply, in an easily-understandable manner.
For the interested musician (and others), this book unveils, in a simple and well-grounded way, what have, until now, been regarded as manufacturer secrets. The examination explores deep within the guitar, including pickups and electrical environment, so that guitar electronics are no longer considered highly secret. With a few deft interventions, many instruments can be rendered more versatile and made to sound a lot better – in the most cost-effective manner.
The author is an experienced electronics professional and active musician. He has thoroughly tested everything described here, in practice.

Dans ce livre, Rémy Mallard initie les débutants à la programmation des microcontrôleurs PIC de Microchip. Après une introduction (pas trop longue) à des principes essentiels de programmation, il propose des chapitres qui regroupent les informations théoriques et pratiques nécessaires à la réalisation de chaque montage.
Il fait la part belle aux « petits » microcontrôleurs 8 bits parce qu'ils sont bon marché et faciles à trouver. Toutefois comme il l'écrit : « ce n'est ni vouloir s'enfermer dans sa coquille, ni faire preuve d'insociabilité, que de s'attacher à ces petites bêtes… Cette famille 8 bits, même si on la qualifie « de base », permet tout de même de disposer de comparateurs, d'oscillateur interne, de modules de conversion analogique/numérique (CAN), de modules de communication à deux fils ou série, de générateurs à rapport cyclique variable entre autres ». C'est pourquoi les réalisations proposées vont bien au-delà du simple chenillard à LED et couvrent un grand nombre de besoins. Le lecteur apprendra comment interfacer des capteurs avec un microcontrôleur, comment acquérir et stocker des données, ou encore comment établir une liaison USB ou Ethernet pour transmettre des données. Toutes ces techniques, combinées les unes avec les autres comme des briques, permettront au lecteur de créer par la suite des montages encore plus ambitieux.
Le logiciel des différents montages est codé en langage Pascal. mikroPascal, l'environnement de développement proposé par MikroElektronika et utilisé par l'auteur, dispose dans sa version gratuite de toutes les fonctions (éditeur, débogueur, simulateur, compilateur, pilotage des programmateurs) de la version payante, mais la taille du code est limitée à 2 Ko (ce qui suffisant pour la plupart des projets du livre). Le lecteur a le choix du programmateur pour transférer le code dans le microcontrôleur (matériel MikroElektronika ou Microchip).
Après la lecture de ce livre, gagné par la bonne humeur communicative de Rémy et fort de sa longue expérience (qu'il partage volontiers), le lecteur n'aura qu'une seule envie : aller plus loin (transposer le code dans d'autres langages, le porter sur d'autres plates-formes de développement, s'attaquer aux PIC32…).
Build your textbook weather station or conduct environmental research together with the whole world. With many practical projects for Arduino, Raspberry Pi, NodeMCU, ESP32, and other development boards.
Weather stations have enjoyed great popularity for decades. Every current and even every long discontinued electronics magazine has regularly featured articles on building your own weather station. Over the years, they have become increasingly sophisticated and can now be fully integrated into an automated home — although this often requires loyalty to an (expensive) brand manufacturer across all components.
With your own weather and environmental data, you can keep up and measure things that no commercial station can. It’s also fun: expand your knowledge of electronics, current microcontroller development boards and programming languages in a fun and meaningful way. For less than 10 euros you can get started and record your first environmental data — with time and growing interest, you will continue to expand your system.

After a short introduction to the Raspberry Pi you proceed with installing the required software. The SD card that can be purchased in conjunction with this book contains everything to get started with the Raspberry Pi. At the side of the (optional) Windows PC, software is used which is free for downloading. The book continues with a concise introduction to the Linux operating system, after which you start programming in Bash, Python 3 and Javascript. Although the emphasis is on Python, the coverage is brief and to the point in all cases – just enabling you to grasp the essence of all projects and start adapting them to your requirements. All set, you can carry on with fun projects.
The book is ideal for self-study
No fewer than 45 exciting and compelling projects are discussed and elaborated in detail. From a flashing lights to driving an electromotor; from processing and generating analog signals to a lux meter and a temperature control. We also move to more complex projects like a motor speed controller, a web server with CGI, client-server applications and Xwindows programs.
Each project has details of the way it got designed that way
The process of reading, building, and programming not only provides insight into the Raspberry Pi, Python, and the electronic parts used, but also enables you to modify or extend the projects any way you like. Also, feel free to combine several projects into a larger design.

Create Models for 3D Printing, CNC Milling, Process Communication and Documentation
Engineers dread designing 3D models using traditional modeling software. OpenSCAD takes a refreshing and completely different approach. Create your models by arranging geometric solids in a JavaScript-like language, and use them with your 3D printer, CNC mill, or process communication.
OpenSCAD differs from other design systems in that it uses programmatical modeling. Your model is made up of primitives that are invoked using a C-, Java- or Python-like language. This approach to model design is close to the “mechanical work” done in the real world and appeals to engineers and others who are not a member of the traditional creative class.
OpenSCAD also provides a wide variety of comfort functions that break the 1:1 relationship between code and geometry. This book demonstrates the various features of the programming language using practical examples such as a replacement knob for a LeCroy oscilloscope, a wardrobe hanger, a container for soap dispensers, and various other real-life examples.
Written by an engineer with over 15 years of experience, this book is intended for Linux and Windows users alike. If you have programming experience in any language, this book will have you producing practical three-dimensional objects in short order!

Ce qui se passe en électronique est par définition invisible à l'oeil nu. L'instrument qui permet précisément de rendre visibles les signaux électriques, celui par le truchement duquel les effets de l'électronique se manifestent à nous, c'est l'oscilloscope.
Hélas, quand on commence à faire de l'électronique, c'est souvent sans oscilloscope. Et l'on en est réduit à tâtonner, aussi bien physiquement que mentalement. Le jour où l'on goûte à la visualisation des signaux sur un écran, c'est une révélation. Plus personne ne souhaite se priver de cet enchantement. Pas de retour en arrière. En électronique, si l'on veut progresser dans le plaisir et dans la compréhension, il faut un oscillo.
Commence alors une période d'interrogation : comment choisir ? Et à peine cette question-là aura-t-elle trouvé sa réponse, il en viendra une ribambelle d'autres que l'on peut résumer en une seule : comment se servir de l'oscilloscope de telle sorte que ce qu'il affiche corresponde bien à la réalité des signaux ?
Dans ce livre, Rémy Mallard, répond clairement à ces questions. Il donne aussi de nombreuses informations pour aider son lecteur à élucider lui-même de nouveaux mystères qui ne manqueront pas de surgir. Ceux qui le connaissent déjà comme l'auteur d'un livre sur l'électronique dont le titre est un programme à lui tout seul : L'électronique pour les débutants qui sèchent les cours mais soudent sans se brûler les doigts, ainsi que d'un livre d'initiation à la programmation des microcontrôleurs PIC, savent qu'ils trouveront ici un ouvrage utile, qu'ils rouvriront souvent.

A Beginner's Guide to AI and Edge Computing
Artificial Intelligence (AI) is now part of our daily lives. With companies developing low-cost AI-powered hardware into their products, it is now becoming a reality to purchase AI accelerator hardware at comparatively very low costs. One such hardware accelerator is the Hailo module which is fully compatible with the Raspberry Pi 5. The Raspberry Pi AI Kit is a cleverly designed hardware as it bundles an M.2-based Hailo-8L accelerator with the Raspberry Pi M.2 HAT+ to offer high speed inferencing on the Raspberry Pi 5. Using the Raspberry Pi AI Kit, you can build complex AI-based vision applications, running in real-time, such as object detection, pose estimation, instance segmentation, home automation, security, robotics, and many more neural network-based applications.
This book is an introduction to the Raspberry Pi AI Kit, and it is aimed to provide some help to readers who are new to the kit and wanting to run some simple AI-based visual models on their Raspberry Pi 5 computers. The book is not meant to cover the detailed process of model creation and compilation, which is done on an Ubuntu computer with massive disk space and 32 GB memory. Examples of pre-trained and custom object detection are given in the book.
Two fully tested and working projects are given in the book. The first project explains how a person can be detected and how an LED can be activated after the detection, and how the detection can be acknowledged by pressing an external button. The second project illustrates how a person can be detected, and how this information can be passed to a smart phone over a Wi-Fi link, as well as how the detection can be acknowledged by sending a message from the smartphone to your Raspberry Pi 5.
