White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...

When designing a handheld device with a color display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...

[Tim] recently found himself tinkering with a cheap string of LEDs. Far from an advanced, IC-controlled addressable set, these were merely a string with LEDs of four colors that could be switched on ...

There are many power management methods that can be used for LED lighting. You can drive them via a number of dedicated driver ICs available on the market, or even use microcontroller units (MCUs) for ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...

Over the years as I've built new PCs I've kept the motherboards from the replaced machines and hung them on the wall. A little bit of geeky artwork. I've decided to dress them up a bit and put them in ...

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 ...

A federal rule that took effect on Tuesday will largely consign one of the world's great inventions — the incandescent light bulb — to the technological dustbin. The rule from the U.S. Department of ...

Getting by without falling under the gaze of surveillance cameras doesn’t seem possible nowadays – from malls to street corners, it’s getting more common for organizations to use surveillance cameras ...
