Gramy melodyjki czyli poznajemy funkcję tone() i bibliotekę pitches.h

Arduino

Polecenie tone() służy do generowania dźwięków przez dowolną płytkę Arduino z ATmega328. Można go używać też ze słabszym procesorem ATtiny85, ale o tym później.

Poniżej specyfikacja:

https://www.arduino.cc/en/Tutorial/toneMelody

POŁĄCZENIE:

KOD:

Aby nasz kod zadziałał musimy dołączyć bibliotekę pitches.h.
W oknie programu Arduino IDE otwieramy zakładkę New Tab, wpisujemy nazwę pitches.h

i kopiujemy zawartość okna poniżej

Kod, który pochodzi ze strony arduino.cc nieco zmodyfikowałem. Postanowiłem zagrać kilka standardów i kawałeczek walca ze Suity nr.2 Szostakowicza.
