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

AIM:-In this project the implementation of code for “Measuring distance of an object using ultrasonic distance sensor (HC-SR04) and also smoothen the sensor data using moving average filter”.

COMPONENTS USED:-

• ARDUINO
• ULTRASONIC DISTANCE SENSOR
• LCD 16*2
• POTENTIOMETER
• RESISTOR(1Kohm)
• CONNECTING WIRE

CIRCUIT:

PROGRAM CODE:

#include
#define trigger 18
#define echo 19
LiquidCrystal lcd(2,3,4,5,6,7);
float time=0,distance=0;
void setup()
{
lcd.begin(16,2);
pinMode(trigger,OUTPUT);
pinMode(echo,INPUT);
lcd.print(" Ultra sonic");
lcd.setCursor(0,1);
lcd.print("Distance Meter");
delay(2000);
lcd.clear();
lcd.print(" Circuit Digest");
delay(2000);
}
void loop()
{
lcd.clear();
digitalWrite(trigger,LOW);
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:");
lcd.print(distance);
lcd.print("cm");
lcd.setCursor(0,1);
lcd.print("Distance:");
lcd.print(distance/100);
lcd.print("m");
delay(1000);
