led light?
i would like to build a led light that has 5 white, 2 red, and 5 blue leds in it. i would like it to have a 3 way switch but it can have what ever you can work in to it. i am very new at doing this so the instructions would have to be very easy and simple. please try to keep it small and cheap please. thank you

This will show you how to wire up the LEDS and what value resistors to use
For the switching it will be easier if you just use a separate switch for each group of LEDs then you can turn them on and off as you require.

Read the link I gave above all LED idiosyncrasies are covered/explained - You have to look round the site.
it is better for each LED to have it's own resistor.
