Servos as live input for other servos

I am wanting to have a servo connected to an arduino mega and be able to use that servo to control another servo connected to the arduino and want it to be controlled live, not recorded then played. Does anyone know whether this is possible, I've seen people use a servo as input and then play it at the press of a button with the same servo. Any help would be great.

I don't understand, can you provide a more detailed explanation.

What are you trying to achieve?

I have no idea how servo A can control servo B.

Is servo B connected to the same Arduino as servo A?


This is the Adafruit feedback servo: And I also don't understand your question.

Maybe just use a pot as the input rather than a servo.
