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 ...

Light effects have always been popular. Now that LEDs are available in all sorts of shapes, sizes and colours for reasonable prices, a whole gamut of possibilities has become feasible. Examples are ...

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 ...

As the name implies, a light-emitting diode (LED) is a semiconductor (diode) that, when forward biased via a voltage/current source, radiates visible light of a particular color (wavelength) and at a ...
