Servo synchronization?

How do I make a servo mimic the movement of a potentiometer or joystick? With the servo trigger it just goes all the way to the end when triggered then moves back. How do I sync the srevo so it will move as I rotated the potentiometer? If I rotate the pot 90D CW, the servo moves with it. If I move it 45 CCW the servo move also.

The servo trigger is meant for ‘triggering’ the servo to a certain set point and returning; you’ll probably want to set that aside and just use a microcontroller, a servo, and a potentiometer like this example https://learn.sparkfun.com/tutorials/sp … rvo-motors
