Ah, but I am using a continuous rotation servo. Do my questions make a little more sense now?
I think the LEDs should reflect the servo, do you agree?
No, they do not. No, I do not.
Do you expect the LEDs to reflect the position of the servo? If so, which position, when? The servos are not commanded to go to a position, so reflecting the position makes no sense.
Therefore, you must mean that you want the LEDs to reflect the speed of the servo, but that doesn't make sense.
