实验箱的蜂鸣器是交流蜂鸣器,在BZSP输入一定频率的脉冲时,蜂鸣器蜂鸣,改变输入频率可以改变蜂鸣器的响声。因此可以利用一个PWM来控制BZSP,通过改变PWM的频率来得到不同的声响,以此来播放音乐。-Experiment Box AC buzzer buzzer is in BZSP certain frequency pulse input, the buzzer beeps to change the input frequency can change the sound of the buzzer. So you can use a PWM to control BZSP, by changing the PWM frequency to get different sounds in order to play music.
