int delay_ms = 5; int buzzer_pin = 9; void setup() { pinMode(buzzer_pin, OUTPUT); } void loop() { digitalWrite(buzzer_pin, HIGH); delay(delay_ms); digitalWrite(buzzer_pin, LOW); delay(delay_ms); }Load the program on the Arduino and the buzzer will emit a low sound....
2、蜂鸣器的选择:在proteus的keyword输入buzzer,有两个结果。ACTIVE表示有源,DEVICE表示无源。要想高电平驱动就要选择ACTIVE的。 3、有源蜂鸣器电路:高电平驱动,低电平驱动可选用PNP管。 4、蜂鸣器电压:蜂鸣器的电压选择2V。笔者亲测电压为 i.MX6ULL终结者蜂鸣器例程原理及原理分析 件。生活中随处可见。 蜂鸣器的...
