Buongiorno a tutti,
Sto cercando di controllare 2 rele con un RTC, voglio che il primo di accenda ad una certa ora (il secondo vediamo più avanti voglio impostare un timer che dopo x minuti dall'avvio del primo si deve accendere il secondo per x tempo).
Per ora, mi funzionano i rele, il sensore funziona, lo schermo funziona e l'RTC funziona.
MA, se mi stampa l'ora in Serial, non riesco a stampare sullo schermo, ne a utilizzare "hour" "minute" "second" "dayOfMonth" ecc altrove che li.
Ad esempio, nella riga evidenziata di giallo, mi sembra non aver sbagliato il codice ma evidentemente lo è perché mi dice che " 'hour' was not declared in this scope"
Perché?!
Grazie a chi vorrà aiutarmi.
(il mio sketch è fatto da più sketch trovati in internet e adattati al mio caso, non sono bravo abbastanza da scrivere da 0)
