I received the goods you sent me well. But not one of ten did not work. The problem is that the chip used is PCF8574T .. The PCF8574AT that I used already had a good chip The ADDRESS value of the existing PCF8574AT is                     "LiquidCrystal_I2C lcd (0x3F, 16,2); // 8574AT" The solution is "LiquidCrystal_I2C lcd (0x27,16,2); // 8574T" You can change it. If you have problems like me, I will help you. Thank you
