Sto usando la libreria “Time” per creare un cronotermostato settimanale con RTC DS3234
Caricando uno degli sketch di esempio ( RTC set) mi perdeva il settaggio dell’ora corrente dopo 4 minuti circa.
Ora ho provato a caricare lo sketch di esempio che gestisce gli allarmi e funziona correttamente.
Penso che quest’ultimo sketch non utilizzi l’RTC ma il clock interno di arduino MEGA.
Chiedo conferma.
Vi allego lo sketch
Ah… Sequalcuno mi spiega come allegare gli sketch al forum senza fare copia incolla lo ringrazio di cuore.
BUON NATALE A TUTTI

* This example calls alarm functions at 8:30 am and at 5:45 pm (17:45)
* and simulates turning lights on at night and off in the morning
* A weekly timer is set for Saturdays at 8:30:30

* A timer is called every 15 seconds
* Another timer is called once only after 10 seconds

* At startup the time is set to Jan 1 2011 8:29 am
