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 ...

There’s something about clocks — sooner or later, every hacker wants to build one. And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment ...

Arduino library for 7-segment LCDs based on the HT1621 driver, with support for 4-digit displays and various low power modes. Often marked as PDC-6X1 (6-digits) or LCM0220 (4-digits). Based on the ...

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 ...

A DIY project from a YouTuber presents the latest version of his 7 Segment Clock, v3.2C. This tabletop clock is built using 3D-printed parts and powered by an Arduino ...

A kitchen timer is one of those projects that’s well defined enough to have a clear goal, but allows plenty of room for experimentation with functionality and aesthetics. [Hggh]’s exploration of the ...
