Analogue Electronics and Microcontrollers Projects Hobbyist electronics can be a fun way to learn new skills that can be helpful to your career. Those who understand the basics of electronics can design their own circuits and projects. However, before you run, you need to learn to walk. It all starts with analogue electronics. You should be familiar with the simple components and circuits and understand their basic behaviors and the issues you may encounter. The best way to do this is through real experiments. Theory alone is not enough. This book offers a large number of practical entry-level circuits, with which everyone can gain the basic experience. Through the widespread introduction of microcontrollers, a new chapter in electronics has begun. Microcontrollers are now performing more and more tasks that were originally solved using discrete components and conventional ICs. Starting out has become easier and easier thanks to platforms including Bascom, Arduino, micro:bit. The book introduces numerous manageable microcontroller applications. It’s now a case of less soldering and more programming.

... 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 !

STmicroelectronics’ wireless IoT & wearable sensor development kit ‘SensorTile.box’ is a portable multi-sensor circuit board housed in a plastic box and developed by STMicroelectronics. It is equipped with a high-performance 32-bit ARM Cortex-M4 processor with DSP and FPU, and various sensor modules, such as accelerometer, gyroscope, temperature sensor, humidity sensor, atmospheric pressure sensor, microphone, and so on. SensorTile.box is ready to use with wireless IoT and Bluetooth connectivity that can easily be used with an iOS or Android compatible smartphone, regardless of the level of expertise of the users. SensorTile.box is shipped with a long-life battery and all the user has to do is connect the battery to the circuit to start using the box. The SensorTile.box can be operated in three modes: Basic mode, Expert mode, and Pro mode. Basic mode is the easiest way of using the box since it is pre-loaded with demo apps and all the user has to do is choose the required apps and display or plot the measured data on a smartphone using an app called STE BLE Sensor. In Expert mode users can develop simple apps using a graphical wizard provided with the STE BLE Sensor. Pro mode is the most complex mode allowing users to develop programs and upload them to the SensorTile.box. This book is an introduction to the SensorTile.box and includes the following: Brief specifications of the SensorTile.box; description of how to install the STE BLE Sensor app on an iOS or Android compatible smartphone required to communicate with the box. Operation of the SensorTile.box in Basic mode is described in detail by going through all of the pre-loaded demo apps, explaining how to run these apps through a smartphone. An introduction to the Expert mode with many example apps developed and explained in detail enabling users to develop their own apps in this mode. Again, the STE BLE Sensor app is used on the smartphone to communicate with the SensorTile.box and to run the developed apps. The book then describes in detail how to upload the sensor data to the cloud. This is an important topic since it allows the sensor measurements to be accessed from anywhere with an Internet connection, at any time. Finally, Pro mode is described in detail where more experienced people can use the SensorTile.box to develop, debug, and test their own apps using the STM32 open development environment (STM32 ODE). The Chapter explains how to upload the developed firmware to the SensorTile.box using several methods. Additionally, the installation and use of the Unicleo-GUI package is described with reference to the SensorTile.box. This PC software package enables all of the SensorTile.box sensor measurements to be displayed or plotted in real time on the PC.

The Basics, New Ideas & Applications Build digital electronics from the ground up—and take it all the way to practical circuits you can use. This book guides you through the core principles of digital technology with a strongly hands-on approach. You’ll begin with the essentials: signals, devices for working with them, and what "logic 0" and "logic 1" mean in real hardware. Simple demonstration setups made from easy-to-find parts (LEDs, diodes, resistors, switches) help you see how logic behaves, making the theory click before you move on. From there, you’ll explore a wide range of logic elements and how they’re implemented, including classic logic families such as TTL and CMOS. The fundamentals section covers the building blocks of digital systems: flip-flops, Schmitt triggers, registers, counters and dividers, encoders/ decoders, multiplexers/demultiplexers, plus A/D and D/A conversion and timing circuits. Next, the book invites you into "new ideas" in digital electronics—universal logic elements, unconventional approaches (including thyristor-based and fractional logic), and creative logic functions that can inspire original designs. Finally, a large, well-organized collection of application circuits turns knowledge into projects: electronic switches and selectors, pulse generators, PWM regulators, frequency multipliers/dividers, phase shifters, and digital filters. Study it deeply, and you’ll gain not only understanding—but the ability to design and debug digital circuits independently.
