LEDs are a wonderful technology. You put in a little bit of power, and you get out a wonderful amount of light. They’re efficient, cheap, and plentiful. We use them for so much! What you might not ...

This is a story about a successful system that nevertheless failed to make the cut. An experimental LED brightness adjustment is something [Mitxela] explored in a project for a high-precision clock; ...

While LEDs are common in voltage detection applications, I have never seen an LED circuit that is dedicated to indicating the presence of low values of current flow. This simple LED current sensor ...

Makers, developers and hobbyists that enjoy creating projects using the Arduino platform may be interested in a new Arduino prototyping tool in the form of the Lumioto. The Lumioto has been created by ...

This circuit shows how to use an ordinary LED as a light sensor. It makes use of the photovoltaic voltage developed across the LED when it is exposed to light. LEDs are cheaper than photodiodes and ...

For setups that rely on stored water, clear awareness of tank level and water quality is essential. Traditional level ...

Allegro has made an led driver with a neat twist – it includes a magnetic Hall sensor. Via a pin, the leds can be set to come on when the magnet is near, or off when the magnet it near – it works with ...

LED chip packaging house Bright Led Electronics has landed orders for one billion infrared LED sensor modules worth NT$2 billion (US$66.7 million) through a China-based maker of LED whiteboards, with ...
