What I am trying to accomplish is that after the ring makes one revolution, it add's one LED onto the start
I don't understand that this means. Do you want to turn 24 LEDs on, one at a time, with a definite interval between them, then turn all but one off. On the next iteration, turn 23 LEDs on, with the same interval between them? Or a different interval?
Please try again, to describe what you want to do.
PS: Whatever it is, it is possible.
