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

*...OFFLINE BATCH...*

Measuring the distance using ultrasonic sensor :-

float avg;
int i,sum;
int duration,inches;
float Duration_inch;
int data[5];

void setup()
{
Serial.begin(9600);

}

void loop()
{
float average = mov_avg();
Serial.println("distance value is");
Serial.println( inches);
delay(1000);
}

void US_Tx()
{
pinMode(7,OUTPUT);
//delayMicroseconds(5);
digitalWrite(7,LOW);
delayMicroseconds(2);
digitalWrite(7,HIGH);
delayMicroseconds(5);

}
float US_Rx()
{

return Duration_inch;
}
