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 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 ...

Arduino is a very popular open-source platform and Arduino UNO is one of the most loved microcontrollers among electronics hobbyists worldwide. It consists of a physical programmable circuit board and ...

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.

I'm using dual 7-segment LED displays in another project, but I figured I could have designed that using fewer GPIO pins than I did. So I tried out my theory here. Now, first things first. You would ...

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 ...
