LEDs for Beginners

LED - Light Emitting Diode:

Led bulbs are a majors component of an electronics project and any DIY project maker and Hobbyist should have some basic led:

3 mm led : Power Consumption is very less runs on low voltage.

5 mm led : Power Consumption is very less runs on low voltage.

8 mm led: Little more power consumption.

Leds can be used to make different types of led sign boards,Led Bulbs and many interesting things.

These can be expensive to buy if you are not buying from correct place so we decided to make a kit containing 100 pcs of multicolored, it includes :

* 50 pc of 3mm leds-Red,Blue,Green,White,Yellow (10 pcs of each color)

* 50 pc of 5mm leds-Red,Blue,Green,White,Yellow (10 pcs of each color)

You Can Buy It Only for $ 0.98 (100pcs) click link below:

Light emitting diodes, commonly called LEDs, are real unsung heroes in the electronics world. They do dozens of different jobs and are found in all kinds of devices. Among other things, they form numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on. Collected together, they can form images on a jumbo television screen or illuminate a traffic light.
Basically, LEDs are just tiny light bulbs that fit easily into an electrical circuit. But unlike ordinary incandescent bulbs, they don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The lifespan of an LED surpasses the short life of an incandescent bulb by thousands of hours. Tiny LEDs are already replacing the tubes that light up LCD HDTVs to make dramatically thinner televisions.
