yes, you are spot on
I gave two different sample scenarios when I said, "Are you trying to blink the led once; move the servo 90 degrees then blink the led again? Blink the led every 10 degrees while the servo moves from 10 to 40 degrees?"
Which one are you saying yes to? (I was just trying to elicit some detail).
Again, what is it you are trying to do?
If you won't tell us what your objective is, then we cannot help.
