Configuratia hardware:

-printr-o rezistenta de de 100 ohmi se conecteaza firul rosu(+) al difuzorului  la pinul 8 (digital) al placutei arduino;
-firul negru se leaga la masa. 





Pentru a genera note muzicale, kitul Arduino necesita utlizarea functiei " tone() " .
Sintaxa functiei tone() este urmatoarea:

tone(pin, frecveta)
tone(pin, frecventa, durata)
Semnificatia parametrilor functiei:
-pin: pinul de iesire care va genera notele muzicale;
-frequency: frecventa notelor in hertzi-este o variabila de tip unsigned int
-duration: durata notei in milisecunde-este o variabila de tip unsigned long
