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 ...

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 ...

For this project you will need 1 Arduino UNO R3, 1 Cathode 7 Segment Display and 7 220 Ω Resistors.

What do you do with 144 7-segment displays? If you’re [Frugha] you put them all together to create an epic clock. Each display has 8 individual LEDs — 7 segments, and a decimal point. Put that all ...

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 exact time and date are obtained from the Network Time Protocol via Wi-Fi. For a smaller display, about 0.8-inch schematic diagram is very simple. Problems are with large segments, containing more ...

This week’s selection is the 3D Printed Electromechanical 7-Segment Display by Instructables contributor tin-foil-hat. If you’re old enough you might recall the pre-LCD digital displays found in clock ...
