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 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 ...

LED (Light Emitting Diode) An LED is a semiconductor device that emits light when current flows through it. LEDs are commonly used in electronics to indicate status or provide visual feedback.

For those of us who remember LED calculators, the HP 5082-7400 series red “bubble” displays hold a special charm. Available in 3, 4, or 5-digit varieties, these multiplexed 7-segment displays provided ...

Over on the [Behind The Code with Gerry] YouTube channel our hacker [Gerry] shows us how to emulate a 74LS48 BCD-to-7-segment decoder/driver using an Altera CPLD Logic Chip From 1998. This is very ...
