hallo i have problem with my program. my program work if i use serial monitor but don't work if I add lcd.print on void loop(). its just stuck at first condition without any progress. please help where should i do to my project. here is my code.
//perkenalan lcd
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x3F,16,2);
