Really slow fade in

Hi,
I'm wanting to make a light to fade in over 10 minutes then stay on for 15 minutes then turn an input to high for 1 second.
Any ideas on how to code this?
Thanks in advance.

That's a pretty basic sketch. I'm sure if you have a go at it, and post your code here people will offer their suggestions/help

What kind of light ?

What kind of input?

Ive tried using the fade in example and adding a delay between it making the number and writing it to the led...

i want to run about 4 led's. and i meant to use an out put, i'm going to hook it up to my ipod dock so it stops playing the music when the lights are fully lit.
