First watch this full video. only then. Start making this project. 

//Arduino Code//

#include <LiquidCrystal.h>char str[34],L=2;
int draft=0,i=0;
int Pass=0,p=0;
 int c,x,d;

LiquidCrystal lcd(11,10,5,4,3,2);

void setup()
{
 Serial.begin(9600);
    pinMode(7,OUTPUT);
  lcd.begin(16, 2);
  
 
}


void loop() 
{ 
  if(draft==1)
  {
    check();
     draft=0;
    i=0;
    delay(1000);
  }
  
}

void serialEvent() 
 {
      while (Serial.available()) 
      {
      char inChar=Serial.read();
      str[i++]=inChar;
      delay(10);
      }
       for (p=i+1;p<34;p++)
      {
        str[i++]=32;
      }
    draft=1;
  Serial.write(str);
  lcd.setCursor(0, 0);
 lcd.print(str);
  if(i>16)
  {
    d=16;
    for (x=0;x<=17;x++)
    {
    lcd.setCursor(x,2);
    lcd.print(str[d]);
    d++;
    }
  }
 }

void check()
{
if(!(strncmp(str,"1",1)))
  {
   digitalWrite(7,50); 
   lcd.clear(); 
  }
  else if(!(strncmp(str,"2",1)))
  {
   digitalWrite(7,LOW);
   lcd.clear(); 
  }
}
