    硬件原理图通过硬件原理图可知，图中三极管用了PNP型，所以要使蜂鸣器发声只要给单片机，由此可以为下文的程序编写提供关键参考。9．4．4程序设计01#include0203sbitBUZZER=P3^7;0405voidmain(void)06{07BUZZER=0;08while(1);09}9．4．5代码分析序号1：包含51单片机寄存器定义地头文件序号3：位定义蜂鸣器为序号5-9：main程序序号7：使，蜂鸣器发声序号8：循环等待9．5继电器实验在现代自动控制设备中，都存在一个电子电路（弱电）与电气电路（强电）的互相连接问题，一方面要使电子电路的控制信号能够控制电气电路的执行元件（如电动机、电磁铁、电灯等），另一方面又要为电子线路的电气电路提供良好的电隔离，以保护电子电路和人身的安全。继电器便能完成这一桥梁作用。9．5．1实例功能本实例通过单片机来控制继电器吸合、释放，读者可以熟练掌握继电器的使用方法。在本例中读者也可以用继电器的常开、常闭触点控制电灯的亮灭，实现“以小控大”。图9-14继电器实验演示图9．5．2器件和原理继电器是一种电子控制器件，它具有控制系统（又称输入回路）和被控制系统（又称输出回路），通常应用于自动控制电路中。它实际上是用较小的电流去控制较大电流的一种“自动开关”。 蜂鸣器的作用 蜂鸣器是一种一体化结构的电子讯响器。宝山区AD16系列蜂鸣器型号
