You look so handsome, it must be a very large bother to select who had the best answer as a thank-you for unpaid assistance.

Since , i am new on instructables, so i had no idea about The best answer thing.

Actually, I found all the answers quite helpful, so could not decide the best one.

I appreciate with your point, so i will take care of this thing by now.

It is hard to decide which answer helped the best for you.

On rare occasions I gave every good answer a patch as a thank-you .

Connect both to a power supply, and look at them through a digital camera - the emitter will look bright.

Right. Connect each to a power supply, appropriate to driving a small LED, like maybe a 1K, or 500 ohm, resistor, in series with a 5 volt supply. Then the one that emits IR light can be seen through the camera's viewfinder.

You'll also want to note that some cameras have ir filters, for example, the iphone 4 has a ir filter on the back cam, but on thefront cam it doesnt. so look around and test a couple of cameras beforew you make conclusions

Usually the "black" one is the receiver and the clear one the transmitter.
The dark color is to block out visible light that might otherwise interfere with the reception.
