Po wprowadzeniu zmiany w programie LCD działa tak samo jak do zmian,

Kod:

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}#include <Wire.h>
//#include <LiquidCrystal_I2C.h>
#include "LiquidCrystal_I2C.h"                 //          zmiana
LiquidCrystal_I2C lcd(0x27, 16, 2);

void setup() {

  lcd.init();
  lcd.backlight();
  lcd.print("Hello, world!");
}

void loop() {
  // put your main code here, to run repeatedly:

}

po dodaniu zmodyfikowanego kodu do foldera
