Handy link to calculate proper resistor's to use

[Artieiii]

I found this link a few days ago so I thought I would share it.
This site allows you to calculate the proper resistor and wattage based on the voltage and current rating of your chosen LED's and calculates the nearest resistor needed.

Here is a screenshot of 1 example i used:

Next time you go to Radio Shack you will know exactly what to buy.
Keep this link in your bookmarks, you may need it someday!
