The New Light-responsive Nano LEDs
https://www.electronics-lab.com/new-light-responsive-nano-leds/
A team of researchers from the US and South Korea reported a unique type of NanoLEDs with unprecedented brightness levels, that excess 80,000 cd/m2, and also can operate both as light emitters and light detectors. These new LEDs are about 50nm long and 6nm in diameter. As described in the paper, they included quantum dots […]
Arduino-Based VU Meter
https://www.electronics-lab.com/arduino-based-vu-meter/
The voice unit (VU) meter is a device that displays a representation of the signal level in audio equipment. It is used in some consumer audio equipment for utilitarian purposes such as in recording devices or for aesthetics like playback devices. The original VU meter is a passive electromechanical device, but using a few LEDs […]
