Due to the advantages like low voltages, long life, cheap, reliable, fast on-off switching etc, the LED’s are used in many applications. The various applications of LED are, All kinds of visual ...

In this simple but effective project, you will learn how to make a simple circuit using a 9-volt battery, LED, and pencil drawing. This project is a fun way to explore and learn about the science of ...

In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

So, your company has decided that it has either found a niche market or an industrial customer(s) with a sufficiently large volume to justify a business case for some kind of LED lighting. Now what?

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 ...

1.1. Connect one end of the alligator clip or wire to the positive terminal of the battery. 1.2. Connect the other end of the alligator clip or wire to the positive lead of the LED bulb (the longer ...
