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 ...

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.

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 ...

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 ...
