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; ...

The CZ-V20 series sensor integrates illumination optics and receiver circuitry in the sensor head to deliver enhanced detection with improved stability. High-power illumination comes from the sensor's ...

Need a cheap and easy way to deter intruders? For homeowners, outdoor lighting is a game changer for providing a line of sight on potential trepassers without running up costly energy bills. If you're ...

The project illustrates how LEDs provide current flow from light when put in backward position. The output of the photodiode needs to be amplified for the light-detection signal to be useful in most ...

The light can be tilted to shine where you need it ...
