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 ...

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 ...

Sometimes you need to display a number nice and large, making it easily readable at a good distance. [Lewis] has just the thing for that: a big expandable 7-segment display. The build is modular, ...

Arduino library for straight-wired 7/14/16 segment displays (each segment with a I/O pin) or shift-register wired displays (data,clock,latch), with/without a decimal point ...

[Sean Hodgins] has a knack for coming up with simple solutions that can make a big difference, but this is one of those “Why didn’t I think of that?” things: addressable seven-segment LED displays.
