Project 2 - Measuring the distance of an object using ultrasonic sensor and also smoothen the sensor data using moving average filter

int triggerPin=6;
int echoPin=7;
long duration;
int distance;

void setup()
{
pinMode(triggerPin, OUTPUT);
pinMode(echoPin, INPUT);
Serial.begin(9600);
}

void loop()
{
digitalWrite(triggerPin, LOW);
delay(200);
digitalWrite(triggerPin, HIGH);
delay(1000);
digitalWrite(triggerPin, LOW);
duration=pulseIn(echoPin, HIGH);
distance=duration*0.034/2;
Serial.print("Distance:");
Serial.println(distance);
delay(200);
