Bog'liq Pezonurlatgich. Pezonurlatgichni boshqarish tonni o‘zgartirish,-www.fayllar.org| tone() funksiyasi chiqishda berilgan chastotada tо‘g‘ri burchakli signal hosil qiladi (50% tо‘ldirish koeffitsiyenli). Bu funksiya shuningdek signal davrini ham bera oladi. Agarda signalning davri kо‘rsatilmagan bо‘lsa Tope () bо‘yicha funksiyasini chaqirilmaguncha signal hosil qilinaveradi. 2 jadvalda notaning birinchi va ikkinchi oktavalar uchun chastotalar qiymati berilgan.
1- rasm. Pyezonurlatgichni Arduino ga ulanish sxemasi.
Notalar bо‘yicha musiqani tuzamiz, melody[] massivga kiritiladi, notalar davrining rо‘yxatini duration [ ] massivga kiritiladi. Notalarni belgilangan axborot notes [ ] massivga kiritiladi, kerakli notalarga tegishli chastotalar haqidagi axborot frequency[ ] massiviga kiritiladi. PASTDA ESA sketch keltirilgan.
2- rasm. Imperiya marshining bir qismi.
