This Arduino project reads Morse code input from a button and displays the decoded letters on a 4-digit 7-segment display. It measures how long the button is pressed to distinguish dots (.) and dashes ...

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 ...

A simple and fully functional digital clock project using 7-segment displays and an ATmega328p/8A microcontroller. Ideal for electronics hobbyists and beginners. Includes circuit instructions, ...

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 ...

The 7-segment display certainly is a popular build, and surprisingly people still come up with new takes on this over a hundred-year-old way to represent numbers. This time ...

Of course, there’s nothing unusual about using 7-segment displays, especially in a clock. However, [Edison Science Corner] didn’t buy displays. Instead, he fabricated them from a PCB using 0805 LEDs ...
