this is a soruce code :--

// ---------------------------------------------------------------------------

// Basic Testing codeed by Robinroy peter.

// ---------------------------------------------------------------------------





#include <NewPing.h>

#include <Servo.h>





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

//plz find servo attach pin is 9..thats defined in setup()

int val; // variable to read the value from the analog pin





#define TRIGGER_PIN 12 // Arduino pin tied to trigger pin on the ultrasonic sensor.

#define ECHO_PIN 11 // Arduino pin tied to echo pin on the ultrasonic sensor.

#define MAX_DISTANCE 200 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.





NewPing ultra_sonic(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.





void setup() {

Serial.begin(115200); // Open serial monitor at 115200 baud to see ping results.

pinMode(13,OUTPUT);

servo.attach(9);

servo.write(val);

}





void loop() {

delay(50); // Wait 50ms between pings (about 20 pings/sec). 29ms should be the shortest delay between pings.

Serial.print("Ping: ");

Serial.print(ultra_sonic.ping_cm()); // Send ping, get distance in cm and print result (0 = outside set distance range)

Serial.println("cm");

digitalWrite(13,LOW);

if((5<ultra_sonic.ping_cm())&&(ultra_sonic.ping_cm()<30)){

digitalWrite(13,HIGH);

servo.write(160-val);

}

val = 160-val;

delay(200);

}
