Social distancing Device for COVID-19 Pandemic

This is a very simple Project. In this I used following components:

• IR Sensor(Infrared Sensor)

• Liquid Crystal I2C Display

• Jumper Wires

• Arduino UNO

• BreadBoard

I had less materials so I used what I was having.

Code Explanation:

1.)Libraries for the Project

#include <Wire.h> 
#include <LiquidCrystal_I2C.h>

2.) Setting the LCD address

LiquidCrystal_I2C lcd(0x27,20,4); 

3.)Setup

void setup(){  lcd.init();                      // initialize the lcd  
lcd.init();  
lcd.backlight();  
lcd.clear();}

4.)Loop

void loop(){  
if(digitalRead(7)==0){  
delay(1000);  
lcd.clear();  
lcd.setCursor(0, 0);  
lcd.print("You are Safe!");}  
if(digitalRead(7)==1){        
lcd.setCursor(0, 0);    
lcd.print("You are'nt Safe!");    }
