We know that LED is a two terminal semiconductor device. It is used in most of the electronic circuits as a sign or visual representation to the normal human to know that circuit is working properly.

Here is the list of best LED based projects along with the circuit diagram, working and applications. LED – Light Emitting Diode. We are all very well know that LEDs are now playing vital role in many ...

High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. This circuit is not complex, but it saved the day in an application involving visual inspection ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

You’ve probably heard of light-emitting diodes, a type of energy-efficient light. While they’re good for practical reasons—say, illuminating a room or a passageway—they can also add a little bling to ...
