Supply Voltage : 5v (usually)
Voltage Drop Across LED : 3.2v (usually.. but depens on LED)
Desired LED Current : 20ma (same as above)

the supply voltage is whatever you are powering off of... voltage drop is the voltage rating of the LED (check the specs) and desired current should be 20-30 ma... 30 is obviously brighter

Did you even stop to think what would happen to these forums if everyone here did that with their threads? To me it seems a little selfish.

when will people learn 100ohm resistor doesn't work with everything. use a resistor calculator.

The same time people start thinking for themselves and actually go out there in search of the knowledge they seek instead of just asking blind and uneducated questions.

I'm sure we're all guilty of that, though. wink.gif

Go to here http://www.lsdiodes.com/THC3/ and click on the color you picked and it will have the specs of the THC3 they are a lil different then a normal LED
