Combining led blink and fade (PWM)

When I said in reply #24

OK. I am glad that I asked for a full explanation because that is very different from your original description.

I did not mean for you to go back and modify your original post.

Now that you have modified it some of the replies to it make no sense.

I still don't know whether

  • All led fade in
  • Stay brightest for 5 seconds
  • All led fade out
  • Stay all dark for 1 second

means that they all fade in and out at the same time or one after the other. Can you please clarify that.
