Pull Down Lever For Highest Score! This Elektor Circuit Classic from 1984 shows a playful application of CMOS 400x series logic ICs in combination with LEDs, a highly popular combination at the time. The project imitates a spinning-digit type slot machine. The Game To play the game, first agree on the number of rounds. Player 1 actuates the switch lever as long as desired and releases it. The LEDs then show the score which is the sum of the 50-20-10-5 digits lit up. If the Play Again! LED lights, Player 1 has another, “free” round. If not, it’s Player 2’s turn. The players keep tab of their scores, and the highest score wins. Features LEDs Indicate Score Multi-Player and Play Again!

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 Elektor Raspberry Pi Buffer Board is there to prevent this! The board is compatible with Raspberry Pi Zero, Zero 2 (W), 3, 4, 5, 400 and 500. 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 400/500. 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 4x TXS0108E ICs by Texas Instruments. The PCB can also be put upright on a Raspberry Pi. Downloads Schematics Layout

Projects Using Arduino IDE and the LVGL Graphics Library The ESP32 is probably one of the most popular microcontrollers used by many people, including students, hobbyists, and professional engineers. Its low cost, coupled with rich features makes it a popular device to use in many projects. Recently, a board called the ESP32 Cheap Yellow Display (CYD for short) is available from its manufacturers. The board includes a standard ESP32 microcontroller together with a 320x240 pixel TFT display. Additionally, the board provides several connectors for interfaces such as GPIO, serial port (TX/RX), power and Ground. The inclusion of a TFT display is a real advantage as it enables users to design complex graphics-based projects without resorting to an external LCD or graphics displays. The book describes the basic hardware of the ESP32 CYD board and provides details of its on-board connectors. Many basic, simple, and intermediate-level projects are given in the book based on the ESP32 CYD, using the highly popular Arduino IDE 2.0 integrated development environment. The use of both the basic graphics functions and the use of the popular LVGL graphics library are discussed in the book and projects are given that use both types of approaches. All the projects given in the book have been tested and are working. The block diagram, circuit diagram, and the complete program listings and program descriptions of all the projects are given with explanations. Readers can use the LVGL graphics library to design highly popular eye-catching full-color graphics projects using widgets such as buttons, labels, calendars, keypads, keyboards, message boxes, spinboxes, sliders, charts, tables, menus, bars, switches, drop-down lists, animations, and many more widgets.

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.
