It's easy to ignore your ethernet port's blinking lights, but in reality these signals could be communicating crucial ...

The ubiquitous LED continues to expand frontiers and applications with a plethora of sizes, colors, and output lumens. Flashing LEDs that incorporate internal electronics for oscillation offer ...

Almost every micro-based project that I have designed in the past 25 years has had a flashing LED, originally as a “health” indicator, but the feature has expanded to use as a status indicator where ...

Nowadays, single-color and multi-color flashing LEDs are easily available, which obviates the requirement of external chips to produce fascinating lighting effects ...

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillator, ...

This is the Visijax wearable, or, to put it another way: a coat. But it’s got a trick quite literally up it’s sleeve, in the form of embedded LEDs that flash when the rider raises his arm to signal a ...

You know how it is. You’ve got that new project running, and while it doesn’t consume much power, it also doesn’t give much indication of whether it’s functioning or just sitting there with a dead ...

This circuit can flash three sets of LEDs with different levels of Flashing. It can be used as Ornamental displays. The circuit uses a simple Astable multivibrator built around the popular timer IC ...
