This repo demonstrates how to work with an Arduino's PWM outputs in a clean programmer-friendly way. It packages all the low-level interaction with timer clocks that underly PWM functionality, ...

Project Description This project uses YOLOv8 for object detection and an Arduino Uno (or Mega) to control an LED. If an electronic device is detected in the camera feed, the LED glows. The system ...

Abstract: This work proposes the use of a high-frequency resonant LLC DC/DC converter with PWM dimming to power an array of LEDs for automotive headlight applications. The resonant tank is designed ...

I've completely swapped my home over to LED lights, and for the most part, I love it. The energy savings are real, and I'm a sucker for all the smart color changing tes. But my biggest grievance is ...

Abstract: This paper presents a pulse-width modulation (PWM) technique for controlling three-phase, four wire voltage source inverters (VSI). It is an extended scheme of a digital scalar pulse width ...

On paper, LED bulbs are made to last for at least several years thanks to their low energy needs. I wanted to know why that doesn't always work out, so I talked to installers and LED manufacturers to ...

Buying a monitor or TV has become a daunting task these days. When manufacturers aren’t branding their products with acronyms like QLED and OLED, they use confusing terms like mini-LED instead.

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.
