Well I bought this piezo speaker ALLDATASHEET.COM - Datasheet search site, Datasheet search site for Electronic Components and Semiconductors and other semiconductors. and it still didn't work.

#include <LiquidCrystal.h>

LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

 }

I changed little part of code and it still didn't work.Can you check code and tell me if something is wrong?
