This is actually the same schematic that you can find on the page. Red leds are connected after the PNP-transistor and blue+green combination is driven by a NPN-transistor. Reason why green led comes on first is because it has lower voltage threshold than the blue leds. They are connect together in parallel with separate current limiting resistors for each led.

another question would a 100k micro potentimeter work instead of a linear to control the speed?
what transistor and capacitor do i use? im a little new to electonics but i can learn quick?

it can't be same schematic because is using only one transistor. How ???? 8O

This to fade single led. If you want to fade five leds on/off at the same time, just connect five leds instead of one. Use for example LedCalc to determine the proper resistors for the led array.
