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<LiquidCrystal.h> //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.
