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.

... qui sèchent les cours mais soudent sans se brûler les doigts Par où commencer pour débuter en électronique ? Vais-je m'égarer en explorant l'internet ? Il regorge de schémas, mais sont-ils fiables ? Me faut-il un livre avec des montages simples ou plutôt un livre sur les composants ? Après trente ans de pratique, l'auteur de ce livre, resté l'éternel débutant qui réalisait lui-même son premier montage des l'âge de dix ans, partage ici sa soif toujours vive d'apprendre. Fin pédagogue, il guide les débutants et répond aux questions que trop de livres laissent en suspens : « Quel type de fer à souder acheter ? »... « Un multimètre à 5 € peut-il suffire ? »... « Un oscilloscope est-il indispensable ? »... « Peut-on installer son montage dans une boîte à cigares ? »... Rémy Mallard démystifie l'électronique en n'utilisant que ce qu'il vous faut de théorie pour aborder joyeusement la pratique sans risque de faire de grosses bêtises. Vous apprendrez à identifier les composants et leur rôle (résistances, condensateurs, bobines, diodes, transistors, relais, commutateurs...) mais aussi à les récupérer, les tester et les ranger. Bientôt vous saurez lire un schéma, choisir vos outils et mettre en boîte vos montages. Rémy connaît toutes les astuces et vous révèle les pratiques à éviter. La matière de cet ouvrage, ce sont des montages simples et ludiques, réalisables sur des plaques d'expérimentation sans soudure: sirène, orgue, chenillard lumineux, interrupteur photosensible, thermomètre, alarme, générateur de picotements, indicateur de niveau de liquide, clignotant à vitesse variable selon la lumière ambiante, indicateur à fenêtre programmable, minuterie avec préavis d'extinction, chenillard de style K2000 (lumineux et sonore), gradateur de lumière à commande infrarouge... Vous commencerez par le code des couleurs et finirez par programmer des PIC !

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.
