This 3D-printed mechanical clock uses three stepper motors controlled by an Arduino Uno and a real-time clock module. Each digit is powered by cam-driven segments with rubber bands helping reset the ...

This guide will walk you through building a digital dice using an Arduino and a seven-segment display. The system generates random numbers (1–6) and displays them on the seven-segment display, ...

Basic BCD Counter using 7447 IC Digital Counter using Arduino Uno 4-bit Synchronous Up/Down Binary Counter using 74192 IC BCD Counter with 7447 IC Uses a 7490 Decade Counter connected to a 7447 BCD to ...

If you need a seven-segment display for a project, you could just grab some LED units off the shelf. Or you could build something big and electromechanical out of Lego. That’s precisely what ...

The 7-segment display is taped and set into the back of the 1/4″ pine with enough brightness to shine through the additional layer of veneer on top. The display is set to show one digit and then ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...
