Inspired by a prank tweet, [Sam Ettinger] endeavored to create an SMD seven-segment display. The NanoRaptor NanoSegment implements a panel of seven-segment display modules sized at “0806” each or just ...

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 circuit was designed to produce a digital roulette that will display the result using a 7-segment LED display. Roulette – refers to a game of chance played at a table where a small ball is made to ...

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, ...

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 ...
