ping and servo

[system]

So I want to make a code that will pan a ping sensor 180 degrees while taking distance readings at constant intervals. Right now, my code makes the servo move very choppily and the ping takes readings at different intervals. Any suggestions?

#include <Servo.h> 
 
Servo myservo; 
 
int pos = 0;     
int pingPin = 2;
long duration, distance;
int previousMillis = 0;
int interval = 100;


void setup() 
{ 
  Serial.begin(9600);
  myservo.attach(9);  
} 
 
 
void loop() 
{ 
  for(pos = 0; pos < 160; pos += 2)  
  {                                  
    myservo.write(pos);     
   pinMode(pingPin, OUTPUT);
   digitalWrite(pingPin, LOW);
   delayMicroseconds(2);
   digitalWrite(pingPin, HIGH);
   delayMicroseconds(5);
   digitalWrite(pingPin, LOW);
   
   pinMode(pingPin, INPUT);
   duration = pulseIn(pingPin, HIGH);
   distance = duration / 29 / 2;
   Serial.print("PING = ");
   Serial.println(distance);
    delay(25);                     
  } 
  for(pos = 160; pos>=1; pos -= 2)     
  {                                
    myservo.write(pos);              
   pinMode(pingPin, OUTPUT);
   digitalWrite(pingPin, LOW);
   delayMicroseconds(2);
   digitalWrite(pingPin, HIGH);
   delayMicroseconds(5);
   digitalWrite(pingPin, LOW);
   
   pinMode(pingPin, INPUT);
   duration = pulseIn(pingPin, HIGH);
   distance = duration / 29 / 2;
   Serial.print("PING = ");
   Serial.println(distance);
    delay(25);                       
  } 
 
}

if you search these forums (exhibition I guess) you can find someone else's attempts to compare to.

You are doing EXACTLY the same thing in the 0 to 160 loop as in the 160 to 0 loop. Create a function to perform the sensor output/input/print stuff, and call that function in both loops.

The servo will stop at each 2 degree increment while the ping sensor is fired. Is that what you mean by

the servo move very choppily

?

Please explain what

the ping takes readings at different intervals

means.
