Salve, sto realizzando un progetto di luci natalizie sincronizzate con la musica. Il mio scopo è quello di comandare tramite il programma Vixen una scheda di relè. Sto utilizzando un codice che gira online poiché non sono molto esperto. Tale codice è in grado di accendere e spegnere i relè random quando Vixen non sta funzionando e di obbedire a Vixen nel caso opposto. Quando provo a compilare ottengo l'errore 'Serial1' was not declared in this scope. Vi allego il codice e vi chiedo aiuto nel capire cosa devo modificare!
