Buna all,de cateva ore ma chinui sa pornesc LCD-ul numai cu trei pini din Arduino si 74HC595 ca registru de shiftare.Folosesc Arduino duemilanove.Am incercat cu toate schemele si librariile pe care le-am gasit.Nu vrea sa porneasca.Specific ca LCD-ul este testat cu sase pini din Arduino si registrii de shiftare merg.Folosesc Arduino 1.0.1 pentru programare.Poate se gaseste cineva care a incercat o schema si o librarie si i-a mers.Multumesc anticipatCatalinLE: LCD ul este 16x2 compatibil HD44780

DS3231 se foloseste intr-un mod similar cu DS1307, doar ca DS3231 include si un Q foarte precis si termo-compensat. Se pot seta 2 alarme si are inclus chiar si un senzor de temp.
