  •  -60% Elex Archief (USB-stick)

    Elektor Classics Elex Archive (USB Stick)

    Het tijdschrift Elex was van 1983 tot 1993 het kleine zusje van Elektor. In Elex werd elektronica op een niet moeilijke en leuke manier uitgelegd. Veel huidige Elektor-lezers zijn ooit begonnen met Elex. Elex is nostalgie. Dat blijkt uit de grote vraag die er steeds is gebleven naar de artikelen en schakelingen uit Elex. Daarom hebben we alle Elex-uitgaven in PDF-formaat op USB-stick gezet. Het gaat om in totaal 120 Elex-nummers, samen goed voor ruim 1400 artikelen, tips en trucs! Deze stick bevat, naast op informele wijze beschreven theorie, een schat aan eenvoudige en leuke schakelingen voor zelfbouw. Alle nummers zijn snel doorzoekbaar en gemakkelijk afdrukbaar.

    Elektor Labs Elektor Raspberry Pi Buffer Board

    When you experiment with the Raspberry Pi on a regular basis and you connect a variety of external hardware to the GPIO port via the header you may well have caused some damage in the past. The Raspberry Pi Buffer Board is there to prevent this! The board is compatible with Raspberry Pi Zero, 3, 4, 5 and 400. All 26 GPIOs are buffered with bi-directional voltage translators to protect the Raspberry Pi when experimenting with new circuits. The PCB is intended to be inserted in the back of Raspberry Pi< 400. The connector to connect to the Raspberry Pi is a right angled 40-way receptacle (2x20). The PCB is only a fraction wider. A 40-way flat cable with appropriate 2x20 headers can be connected to the buffer output header to experiment for instance with a circuit on a breadboard or PCB. The circuit uses four TXS0108E ICs by Texas Instruments. The PCB can also be put upright on a Raspberry Pi 3 or newer. Downloads Schematics Layout

  •  -20% Motor Control Development Bundle

    Elektor Bundles Motor Control Development Bundle

    Electric motors are found in countless electronic appliances and devices in and around our homes. In these devices, motor controllers are used to ensure efficient, safe, and accurate ways to govern the speed or the actuator position of the motor(s) used. Electric motors can be classified as either DC or AC depending on the type of voltage used to control them. DC motors are the oldest type of electric motors and they are widely used by electronics developers both in home labs and in schools and laboratories. Almost all printers, cameras, robots, and CNC machines in consumer, commercial, and industrial applications use some kind of DC motor. AC motors on the other hand are used in many home appliances and tools as they can be powered directly from an AC power outlet. Cytron’s Maker Pi RP2040 Development Board is an advanced system based on the RP2040 processor and developed with motor control applications in mind. The board comes with dual-channel brushed DC motor controller hardware, 4 servo motor ports, and 7 Grove-compatible I/O ports, making it an ideal platform within mobile robotics applications, for robot arm control, or in any other type of application requiring precise control of motors and actuators. The project book, written by well-known Elektor author Dogan Ibrahim, includes over 50 projects using LEDs, a buzzer, an OLED display, an ADC converter, an ultrasonic sensor, PWM, and temperature and humidity control. The main chapters cover DC motor control, servo motor control and stepper motor control using the Maker Pi RP2040 Development Board in creative and educational ways.

    Microcontroller Basics with PIC

    1 review

    In this book the author presents all essential aspects of microcontroller programming, without overloading the reader with unnecessary or quasi-relevant bits of information. Having read the book, you should be able to understand as well as program, 8-bit microcontrollers.The introduction to microcontroller programming is worked out using microcontrollers from the PIC series. Not exactly state-of-the-art with just 8 bits, the PIC micro has the advantage of being easy to comprehend. It is offered in a DIP enclosure, widely available and not overly complex. The entire datasheet of the PIC micro is shorter by decades than the description of the architecture outlining the processor section of an advanced microcontroller. Simplicity has its advantages here. Having mastered the fundamental operation of a microcontroller, you can easily enter into the realms of advanced softcores later.Having placed assembly code as the executive programming language in the foreground in the first part of the book, the author reaches a deeper level with ‘C’ in the second part. Cheerfully alongside the official subject matter, the book presents tips & tricks, interesting measurement technology, practical aspects of microcontroller programming, as well as hands-on options for easier working, debugging and faultfinding.

    RFID Starter Kit for Arduino (incl. Uno R3)

    Modern electronic experimenter kits contain modules that just plug together rather than individual components so that now we can quickly get modules talking and then decide in software how the system behaves. Thanks to the wide selection of software library functions we can have a sketch up and running in no time. These kits are worthy successors to the bags of loose components that were a feature of earlier experimenter’s kits. Electronic newbies, practicing engineers and old hands alike are sure to find that these kits interesting. The range of components is sure to get you thinking what you could use them for and they are a good way to build on your existing knowledge. You’ll have no excuse not to go on to design and build your own system! The ‘RFID Starter Kit for Arduino’ comes in a handy case and contains over 30 state-of-the-art components, devices and modules. Although it contains an RFID receiver module along with two RFID tags in the form of a credit card and key fob, the case is an Aladdin’s cave with loads of other useful components. To begin you will need an Arduino Uno along with the starter kit which amongst other things contains: A humidity sensor; A multicolor LED; A large LED-Matrix with 64 LEDs; 4 x 7-segment LED displays; A handheld IR remote controller plus IR receiver chip; A complete LC-Display module with I²C bus interface. The wide range of peripherals included in the kit ensures the number of different experiments and applications you can build. Two example applications that can easily be built using this box of goodies have been described in an article published in Elektor Magazine: Universal weather station with LC-Display and Door entry system using RFID security. More similar projects have been described in the new book Home Automation Projects with Arduino.
