Hi, i've build a little Pool light with 5 3W RGB LEDs, witch is supposed to have new functions (controlable by a IR Remote), on of them would be fading between random Colors, for that i would like to make a fade function, for that function i need to know the previous PWM Values writen to the LEDs, a…

I don't get why saving a variable is such a big deal.
The value was in a variable when you did the analogWrite, so why not use that again?
