hello all,, So I have a project I want to build. I recently scavenged an RGB LED from a scanner. I tore the scanner apart because I found an instructable to build a cool desk lamp from the super bright white bulb in most scanners.. Well the one found and ripped apart had an RGB LED in it instead of a bulb. So I had a few issues making white light from it, but im getting that worked out with help in another area of the forums here. So I wanted to post this here to keep things separate.. Ok, with that said heres what I want to do.. I did a search of this site to figure out how to get the LED to light white and I read a few guys here talking about using 555 timers to control the colors with PWM. I have a dozen of the 555's and got to thinking about it.. So heres what I want to do... I want to build a desk lamp with the RGB and be able to control the colors with a single switch and some 555's. Now im kinda new to this and ive done a couple of 555 projects so Im not really familiar with the timer. right now im just interested in getting the light to work with a single switch to turn on red, blue, green, and white using 555 timers.. after that's figured out I might want to do some color fading and other cool things with it.. Thanks
