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 ...

The board has four LED arrays resulting in a display of 8×32 LEDs. The MAX7219 takes a 16-bit data word over a 10 MHz serial bus, so programming is pretty easy.

We'll freely admit to having a love / hate relationship with Christmas lights and decorations. The sheer gaudiness of it all often turns our "bah humbug" nature inside out, revealing the awe ...

A more advanced LED system will be in place on all Indy cars beginning with next week’s season-opening race, the March 10 Firestone Grand Prix of St. Petersburg. The LED displays are intended to ...

The first LED lights at 4000 RPM, with subsequent LEDs coming on at each 500 RPM increase beyond that. At 5800 RPM, all the LEDs blink as a redline warning.

Direct view light emitting diode display sales across Korea are likely to increase at 16.2% CAGR. Japan’s direct view LED display industry is forecast to reach US$ 9.1 billion by the end of 2033.

Physicists have created the tiniest light-emitting diode (LED) displays ever 1. The image above was shown on a monochromatic display with pixels less than 100 micrometres across, about the width ...
