#include $LiquidCrystal_I2C.h$ //In this line Please replace $ sign with open and close Angle brackets

//the first parameter is the I2C address

lcd.backlight(); // turn on the backlight
pinMode(RelayPin, OUTPUT); // Set RelayPin as an output pin
}

void loop() {
// Let's turn off the relay...
digitalWrite(RelayPin, LOW);
lcd.clear();
lcd.setCursor(0, 0); //write on the top row
lcd.print("Relay OFF!!!!!");
delay(3000); //wait 3 seconds

// Let's turn on the relay...
digitalWrite(RelayPin, HIGH);
lcd.clear();
lcd.print("Relay ON!!!!!");
