How can I add code for i2 lcd? This is my final project , im building a rf remote for home appliances.

#include <rcswitch.h>
#include <eeprom.h>

RCSwitch mySwitch = RCSwitch();
int LED1 = 3; // load1 Pin out
int LED2 = 4; //load2 Pin out

int load1, load2;

void setup() {\
  
  Serial.begin(9600);
  mySwitch.enableReceive(0);  // Receiver on interrupt 0 => that is pin #2

  load1 = EEPROM.read(1);
  load2 = EEPROM.read(2); 
  
  pinMode(LED1,OUTPUT); digitalWrite(LED1, load1);
  pinMode(LED2,OUTPUT); digitalWrite(LED1, load2);
  delay(100);
  
}

void loop() {
  if (mySwitch.available()>0) 
  {
    
    unsigned long int num = mySwitch.getReceivedValue();
    Serial.print(num);
    switch(num)
    {
      case 255650: mySwitch.disableReceive();
                   load1 = !load1;
                   EEPROM.write(1,load1);
                   break;
      case 255656: mySwitch.disableReceive();
                   load2 = !load2;
                   EEPROM.write(2,load2);
                   break;
       
      
    }
    digitalWrite(LED1, load1);
    digitalWrite(LED2, load2);
    
    unsigned long time_now = millis();
    int ck = 100;
    while(millis() < time_now + ck){;}  
           
     mySwitch.resetAvailable();
     mySwitch.enableReceive(0);
  }
}
