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 ...
Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...
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 ...
A “BLINKING” clue might reveal if someone is really paying attention to what you’re saying or not. That’s the latest from psychologists who say our blinking habits are linked to how hard we’re ...
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 ...
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 ...
Learn how to build an impressive Spider-Man mask with fully movable eyes using simple cardboard and craft materials! This step-by-step DIY tutorial walks you through every stage, from printing ...
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.
