Programming and Projects for the Minima and WiFi Based on the low-cost 8-bit ATmega328P processor, the Arduino Uno R3 board is likely to score as the most popular Arduino family member so far, and this workhorse has been with us for many years. Recently, the new Arduino Uno R4 was released, based on a 48-MHz, 32-bit Cortex-M4 processor with a huge amount of SRAM and flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The new board also supports the CAN Bus with an interface. Two versions of the board are available: Uno R4 Minima, and Uno R4 WiFi. This book is about using these new boards to develop many different and interesting projects with just a handful of parts and external modules, which are available as a kit from Elektor. All projects described in the book have been fully tested on the Uno R4 Minima or the Uno R4 WiFi board, as appropriate. The project topics include the reading, control, and driving of many components and modules in the kit as well as on the relevant Uno R4 board, including LEDs 7-segment displays (using timer interrupts) LCDs Sensors RFID Reader 4×4 Keypad Real-time clock (RTC) Joystick 8×8 LED matrix Motors DAC (Digital-to-analog converter) LED matrix WiFi connectivity Serial UART CAN bus Infrared controller and receiver Simulators ? all in creative and educational ways with the project operation and associated software explained in great detail.

32 new Projects, Practical Examples and Exercises with the Elektor Arduino Nano MCCAB Training Board Electronics and microcontroller technology offer the opportunity to be creative. This practical microcontroller course provides you with the chance to bring your own Arduino projects and experience such moments of success. Ideally, everything works as you imagined when you switch it on for the first time. In practice, however, things rarely work as expected. At that point, you need knowledge to efficiently search for and find the reason for the malfunction. In this book for advanced users, we delve deep into the world of microcontrollers and the Arduino IDE to learn new procedures and details, enabling you to successfully tackle and solve even more challenging situations. With this book, the author gives the reader the necessary tools to create projects independently and also to be able to find errors quickly. Instead of just offering ready-made solutions, he explains the background, the hardware used, and any tools required. He sets tasks in which the reader contributes their own creativity and writes the Arduino sketch themselves. If you don’t have a good idea and get stuck, there is, of course, a suggested solution for every project and every task, along with the corresponding software, which is commented on and explained in detail in the book. This practical course will teach you more about the inner workings of the Arduino Nano and its microcontroller. You will get to know hardware modules that you can use to realize new and interesting projects. You will familiarize yourself with software methods such as ‘state machines,’ which can often be used to solve problems more easily and clearly. The numerous practical projects and exercise sketches are once again realized on the Arduino Nano MCCAB Training Board, which you may already be familiar with from the course book ‘Microcontrollers Hands-on Course for Arduino Starters’, and which contains all the hardware peripherals and operating elements we need for the input/output operations of our sketches. Readers who do not yet own the Arduino Nano MCCAB Training Board can purchase the required hardware separately, or alternatively, build it on a breadboard.

A Combat Guide against E-waste and Throwawayism This book is for anyone who enjoys tinkering with analog and digital hardware electronics. Regardless of the sophistication of your workspace, only basic tools are required to achieve truly satisfying results. It is intended as a reference guide among other hardware repair publications you may have in your library. However, the book goes a step further than most other repair guides in addressing issues in the modern era of discarded electronics called e-waste. E-waste should be put to good use. Producing anything new requires not just precious resources and labor, but also energy to make and deliver it to global retail shelves. Your talents and love of electronics can be put to good use by rescuing and resurrecting at least selected units from this endless stream of e-waste. Examples include either restoring through repair, or salvaging reusable electronic and mechanical components for your next project. Smart tips are provided throughout the book, and much information is tabulated for easy reference. The book expands age-old repair and hacking techniques applied for repair on the workbench into clever methods and applications to achieve effective results with discarded or “non-servicable” electronic consumer products. The final chapter provides real-life examples using all of the previously discussed content in a summarized form for each example repair type.

Menno van der Veen is well known for his research publications on tube amplifiers used in audio systems. In this book he describes one of his research projects which focuses on the question of whether full compensation for distortion in tubes and output transformers is possible. In the past, a variety of techniques have been developed. One of them has largely been forgotten: trans-conductance, which means converting current into voltage or voltage into current. Menno van der Veen has breathed new life into this technique with his research project titled “Trans”. This book discusses all aspects of this method and discusses its pitfalls. These pitfalls are addressed one by one. The end result is a set of stringent requirements for Trans amplifiers. Armed with these requirements, Menno then develops new Trans amplifiers, starting with Transie 1 and Transie 2. These DC-coupled, single-ended tube amplifiers have unusually good characteristics and are suitable for hobbyist construction. Next the Trans principle is applied to amplifiers with higher output power. A trial-and-error process ultimately leads to the Vanderveen Trans 30 amplifier, which optimizes the features of Trans. The characteristics of this amplifier are so special and unique that Menno believes he has struck gold. To ensure that variations in tube characteristics cannot interfere with optimal Trans behavior, Menno makes use of simulations and comparison with other amplifier types. This book reads like an adventure story, but it is much more – it is an account of solid research into new ways to achieve optimal audio reproduction.

Projets d'électronique analogique et de microcontrôleurs L'électronique amateur peut être une façon amusante d'acquérir de nouvelles compétences qui peuvent être utiles à votre carrière. Ceux qui comprennent les bases de l’électronique peuvent concevoir leurs propres circuits et projets. Cependant, avant de courir, vous devez apprendre à marcher. Tout commence avec l'électronique analogique. Vous devez être familier avec les composants et circuits simples et comprendre leurs comportements de base ainsi que les problèmes que vous pouvez rencontrer. La meilleure façon d’y parvenir est de procéder à des expériences réelles. La théorie seule ne suffit pas. Ce livre propose un grand nombre de circuits pratiques d'entrée de gamme, avec lesquels chacun peut acquérir l'expérience de base. Grâce à l’introduction généralisée des microcontrôleurs, un nouveau chapitre de l’électronique s’ouvre. Les microcontrôleurs effectuent désormais de plus en plus de tâches qui étaient initialement résolues à l'aide de composants discrets et de circuits intégrés conventionnels. Débuter est devenu de plus en plus facile grâce à des plateformes telles que Bascom, Arduino, micro:bit. Le livre présente de nombreuses applications de microcontrôleurs gérables. Il s'agit désormais de moins de soudure et plus de programmation.
