DISTANCE MEASURING DEVICE WITH ULTRASONIC SENSOR AND I2C LCD DISPLAY || DIY || REAL-TIME PROJECT

hey! guys I came with a new project distance measuring device for realtime projects.


Components Required:
1. Ultrasonic Sensor.
2. I2C LCD Display.
3. Arduino UNO.

4. USB cable.

5. jumper wires.



Circuit:





Source code:

//please download i2c lcd library at this link:- https://github.com/fdebrabander/Arduino-LiquidCrystal-I2C-library

#include <Wire.h> // Library for I2C communication

#include <LiquidCrystal_I2C.h> // Library for LCD

LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x3F, 16, 2); // Change to (0x27,16,2) for 16x2 LCD.my address is (0x3F)

int trigPin = A0;

int echoPin = A1;

long distance;

long distanceInch;

long duration;

void setup(){

 lcd.init();

 lcd.backlight();

 pinMode(trigPin, OUTPUT);

 pinMode(echoPin, INPUT);

 lcd.setCursor(0,0);

 lcd.print("   WELCOME TO");

 lcd.setCursor(0,1);

 lcd.print("  MKINVENTIONS");

 delay(2000);

}

void loop() {

 ULTRASONIC();

 lcd.clear();

 lcd.setCursor(0,0);

 lcd.print("DISTANCE CM:");

 lcd.print(distance); 

 lcd.setCursor(0,1);

 lcd.print("DISTANCE INCH:");

 lcd.print(distanceInch); 

// lcd.setCursor(0,1);   

// lcd.print("DISTANCE MM:");

// lcd.print(distanceInch); 

}

void ULTRASONIC(){

  digitalWrite(trigPin, LOW);

  delayMicroseconds(2);

  digitalWrite(trigPin, HIGH);

  delayMicroseconds(10);

  digitalWrite(trigPin, LOW);

  duration = pulseIn(echoPin, HIGH);

  distance = duration*0.034/2;

  distanceInch = duration*0.0133/2;

}
