help needed abt bi colur led

LOL!

I can't decide whether that's funny or cruel :D ________________________________________ The Grim Reaper

i already tried that .i didnt get what i expected so i was here thinking that some may know the related sites that can have the full constructional details.

hey end up its the first time i was searching for the bicolur led. i dont even know how they work. so i thought some may help me. now i tried and i know the bicolur led its bit small abt the construction than i expected it would be. anyhow thank you

Hi, Nitin. If you're still there, I would have suggested you first try to get the manufacturer's part number or some more information -- at least, whether it's a two- or three-lead device.

Two lead bi-color LEDs are made with inverse-parallel diodes, like this (view in fixed font or M$ Notepad):

| ~ | R~ | o---o--|

But if you expect real answers, you need to actually ask proper questions.

In your original post, you said: "i need information abt bi colour leds.pls direct me to the site which can give me the constructional details abt bi colur leds thanks"

That says nothing about what information you need, it doesn't indicate whether you are asking how to make them or how to connect them, and it sure doesn't convey anything about why you couldn't do some searches yourself (or that you did and weren't successful).

If you'd said "I no bi-color LEDs can show two colors, but I don't understand how they work...." that might have gotten some answers. Or "I know you can change the colors of these by reversing polarity, but I don't understand how I can do that in a circuit...." There are likely lots of questions you could ask that would get a response far better than your vague original post, because then it would be clearer exactly what it is you want to know, and give us an idea of where you are on the electronic knowledge tree, so there'd be an answer to provide, and in terms that you could understand.

If people can't ask proper questions, then they shouldn't get upset when they don't get the answer they want. Because it's not the people trying to be helpful that are at fault, but the original question that gives them little to work with.

Note that even a properly phrased question does not get an automatic answer. People aren't here to answer questions, they are here for a variety of reasons and they answer questions when they feel like it. Badly phrased questions provide less incentive to bother, but even a good question may get the "do a websearch" for the simple reason that the person replying has decided it doesn't deserve a better answer.

First, spelling helps a lot. Grammar helps make your intentions clear as well.

I know I'm a newbie in this forum, but this thread seems to be heading in this direction:

Once you learn to ask the right questions, any decent search engine will tell you what you need to know. You can't use bad spelling and abbreviations to find anything online.

The word tutorial, along with proper spelling will usually ring up plenty of useful pages of information. "Datasheet" will do the same, if you have a good description, or even better, a part number.
