Code Writer (Consultant) ... Help Needed

[Argo]

We are running a teensy 4.0 between a potentiometer and a servo.

Need help writing code that provides smooth servo-motion while "stopping" at the correct points along the arc of rotation.

I have regularly found it cheaper to use these than pay to develop the code needed to smoothly arrive on target: https://www.robotis.us/dynamixel-ax-12a/

#include <Servo.h>

Servo myservo;  // create servo object to control a servo

int potpin = 0;  // analog pin used to connect the potentiometer
int val;    // variable to read the value from the analog pin

void setup() {
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop() {
  val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023)
  val = map(val, 0, 1023, 0, 180);     // scale it to use it with the servo (value between 0 and 180)
  myservo.write(val);                  // sets the servo position according to the scaled value
  delay(15);                           // waits for the servo to get there
}
