LEDs are small but powerful components that light up everything from phone screens to flashlights. In this video, you'll learn how a tiny chip inside an LED converts electrical energy into light using ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

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 ...

Scientists have uncovered the mystery of why blue light-emitting diodes (LEDs) are so difficult to make, by revealing the complex properties of their main component -- gallium nitride -- using ...

It turns out the "10-year lifespan" printed on your LED box is often a total fantasy. I spent years falling for the marketing, only to end up standing on a ladder every six months replacing bulbs that ...

More than one-fifth of US electricity is used to power artificial lighting. Light-emitting diodes based on group III/nitride semiconductors are bringing about a revolution in energy-efficient lighting ...

The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original. Researchers studied the ...

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 ...

Porcupine is a highly-accurate and lightweight wake word engine. It enables building always-listening voice-enabled applications. It is Sensitivity is the parameter that enables developers to trade ...

This library currently supports any board based on the ATmega168, ATmega328P, ATmega32U4, or ATmega2560 which runs at 8 MHz, 16 MHz, or 20 MHz. The LED strip's input connector has two pins that should ...

Abstract: This paper proposes a low-cost platform for real-time monitoring PV panel operation. The data acquisition is performed using inexpensive hardware. The real-time data measurements (current ...
