chỉ cần nối ra cái loa từ chân rc0
mà cái này thích thì khai báo lại. nhưng mà có cái sao âm thanh nó không hay lắm bác nào biết làm thế nào để tạo ra âm thanh hay thì giúp mình với.mắt dô mấy cái mạch lọc rc thì nó lại bị rè rất khó chịu
định dung pwm nhưng phải tạo lại từng nốt. về cái tần số bên pwm tính toán cũng khó qua!!!!!
