6、有源蜂鸣器和无源蜂鸣器 (1)有源蜂鸣器(Active buzzer)内建了一组固定的频率,只要接通电源,就会发出固定的音调。蜂鸣器的源,这里指的是震荡源。也就是说有源蜂鸣器内部带有多谐振荡器,可以产生 1.5kHZ-2.5kHZ 的电压信号,由此有源蜂鸣器才能发声。有源蜂鸣器、无源蜂鸣器的外型很像,一般有源蜂鸣器会在上面贴一...
The active buzzer has an internal source of oscillation, so it will be called as soon as it is energized.Program control is convenient vcc,gnd,io,那么io引脚需要接入一个digital引脚,并在代码中指出,设定引脚模式,同时,如果是使用digitalWrite(),那么High,LOW,交替出现才可响声 如果是使用tone(),则较为...
