Build Your Own Vintage Radio Broadcaster The Elektor AM Transmitter Kit allows streaming audio to vintage AM radio receivers. Based on a Raspberry Pi Pico microcontroller module, the AM Transmitter can transmit on 32 frequencies in the AM band, from 500 kHz up to 1.6 MHz in 32 steps of approx. 35 kHz. The frequency is selected with a potentiometer and shown on a 0.96" OLED display. A pushbutton allows toggles the transmitting mode between On and Off. The range of the transmitter depends on the antenna. The onboard antenna provides a range of a few centimeters, requiring the AM Transmitter to be placed close to or inside the radio. An external loop antenna (not included) can be connected to increase the range. The Elektor AM Transmitter Kit comes as a kit of parts that you must solder to the board yourself. Features The board is compatible with a Hammond 1593N enclosure (not included).A 5 VDC power supply with micro-USB connector (e.g., an old phone charger) is needed to power the kit (not included). Current consumption is 100 mA. The Arduino software (requiring Earle Philhower’s RP2040 Boards Package) for the Elektor AM Transmitter Kit plus more information is available at the Elektor Labs page of this project.

De mens is van nature uitgerust met sensoren voor geluid, licht, geur, smaak en gevoel. Zintuigen die met elektronica slechts ten dele gekopieerd kunnen worden. Met de Elektor sensorkit kunnen we wel aardig in de buurt komen. Sensoren kunnen elektronica aansturen, maar ze kunnen ons ook van informatie voorzien. Daarom vormt niet alleen het meten van grootheden, maar ook het zichtbaar maken ervan via de Arduino seriële monitor een niet onbelangrijk deel van dit boek. De microprocessor ATtiny85 die de Arduino-taal begrijpt, maakt het experimenteren met sensoren gemakkelijk en goedkoop. We zullen niet snel een Arduino-kaartje vast solderen in een permanente opstelling. Bij een achtpotige ATtiny zal dat geen schuldgevoel opleveren. Dat neemt niet weg dat alle sketches gewoon op elk Arduino-board draaien met mogelijk hier en daar een aanpassing van pennummers omdat die kunnen verschillen met reguliere Arduino-boards. We zullen uitgebreid aandacht besteden aan het programmeren van de ATtiny. Veel schakelingen zijn bruikbaar in het natuurkundepracticum op school of voor bedrijfsmatige toepassingen. Maar de nadruk ligt toch wel op de (beginnende) elektronicahobbyist die zijn vrije tijd op een leuke maar vooral ook nuttige manier wil besteden. Want meer dan ooit tevoren heeft techniek de toekomst.

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.

Verwirklichen Sie Ihre Projekt-Träume: Der Kilometerzähler fürs Hamsterrad, eine vollautomatische Steuerung Ihrer Ameisenfarm mit Webinterface, oder den Sandwich-O-Mat – eine Maschine, die Sandwich-Toasts nach Wahl belegt und überbackt. Mit dem Arduino und der DIY- oder Maker-Bewegung wurde nicht nur der Einstieg in die Mikrocontroller-Programmierung kinderleicht, auch eine zweite Entwicklung fand statt: Findige Entwickler brachten kleine Boards – sogenannte Shields oder Module – auf den Markt, die den Einsatz von zusätzlicher Hardware stark vereinfachten. Die kleinen Baugruppen enthalten alle wichtigen elektronischen Teile, um mit ein paar Steckkabeln an den Mikrocontroller angeschlossen zu werden, so dass ein frickeliger und aufwändiger Aufbau auf dem Steckboard entfällt. Zudem ist es so möglich, auch winzig kleine Bauteile zu handhaben, die keine Anschlussbeinchen mehr haben (sogenannte SMDs).

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, and this workhorse has been with us for many years. Eleven years later, the long-overdue successor, the Arduino Uno R4, was released. It is built around a 48 MHz, 32-bit Arm Cortex-M4 microcontroller and provides significantly expanded SRAM and Flash memory. Additionally, a higher-precision ADC and a new DAC are added to the design. The Uno R4 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. 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 4x4 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.
