#include <LiquidCrystal.h>

const int ledPin =  6;
int buttonState = 0;
String x;
String str;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {

pinMode(ledPin, OUTPUT);
Serial.begin(9600);
lcd.begin(16, 2);
digitalWrite(ledPin, HIGH);

}

void loop () {

if(Serial.available() > 0)
{
x = Serial.readString();
lcd.clear();
lcd.print(x);
if (x==“LED OFF”){

digitalWrite(ledPin, LOW);
}
else{
digitalWrite(ledPin, HIGH);
}
}

}
