A common display found on digital watches and readouts that looks like a series of 8s. Each digit is formed by selective illumination of from one to seven separately addressable segments. For more ...

Mechanical multi-segment displays have become quite a thing lately, and we couldn’t be more pleased about it. The degree of mechanical ingenuity needed to make these things not only work but look good ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

We’ve been displaying numbers using segmented displays for almost 120 years now, an invention that predates the LEDs that usually power the ubiquitous devices by a half-dozen decades or so. But LEDs ...

The project is a 12” digit height 7-segment display which was made from 15×4 LEDs wherein 4 LEDs are connected in series and fifteen times in parallel arrangement. The project is a 12” digit height ...

Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired as a shift register, ...
