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

ANSWER:-

AIM:-

             To  implement the code for “Measuring distance of an object using ultrasonic distance sensor (28015 Ping) and also smoothen the sensor data using moving average filter”.

COMPONENTS REQUIRED:-

• BREADBOARD
• ARDUNIO
• RESISTOR
• ULTRASONIC DISTANCE SENSOR
• CONNECTING WIRE
• POTENTIOMETER
• LCD 16*2

CODE OF THE PROJECT:-

#include           //Header to use LCD functions

#define trigger 18

#define echo 19

LiquidCrystal lcd(2,3,4,5,6,7);         //pins connected to LCD

float time=0,distance=0;

void setup()

{

lcd.begin(16,2);    //To begin LCD display        

pinMode(trigger,OUTPUT);       //declaring pin2 as output

pinMode(echo,INPUT);

lcd.print(" Ultra sonic");            //To display in LCD

lcd.setCursor(0,1);

lcd.print("Distance Meter");     //To display in LCD

delay(2000);

lcd.clear();

lcd.print(" Circuit Digest");   //To display in LCD  

delay(2000);                      //delay    

}

void loop()

{

lcd.clear();

digitalWrite(trigger,LOW);    //sensor is triggered by pin 2 as output

delayMicroseconds(2);

digitalWrite(trigger,HIGH);

delayMicroseconds(10);

digitalWrite(trigger,LOW);

delayMicroseconds(2);

time=pulseIn(echo,HIGH);

distance=time*340/20000;

lcd.clear();

lcd.print("Distance:");          //to display in LCD

lcd.print(distance);

lcd.print("cm");           //To display in LCD

lcd.setCursor(0,1);

lcd.print("Distance:");

lcd.print(distance/100);      //To display in LCD

lcd.print("m");

delay(1000);        //delay

}

OUTPUT:-

it was showing the distance of an object in the LCD.
