Electronics are a hot topic today, and kids are eager to master the fundamentals of this interesting and important branch of technology. Here is a basic electronics course for kids that will teach and ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

The light-emitting diode (LED) keeps making inroads into everyday electronics. From displays to bulbs to headlamps and other lamps in newer vehicles, this device is producing brighter, more attractive ...

The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...

Engineers have developed a new way to make sharper, defect-free displays, which could improve augmented and virtual reality devices. Instead of replacing red, green, and blue light-emitting diodes ...

Physicists in Japan have made a diode that emits light at the shortest wavelength ever. The device, made by Yoshitaka Taniyasu and colleagues at NTT Basic Research Laboratories in Atsugi, is made from ...

Take apart your laptop screen, and at its heart you’ll find a plate patterned with pixels of red, green, and blue LEDs, arranged end to end like a meticulous Lite Brite display. When electrically ...
