Note: The following programs have been debugged by me and are successful.

Purpose: buzzer sound

The procedure is as follows:

#include
sbit buzzer=P3^5;
void delay02s (void)   //延时蜂灵
{
unsigned x,y,k;
for(x=10;x>0;x--)
for(y=10;y>0;y--)
for(k=248;k>0;k--);
}
void main(void)      //主程序
{
while(1)
{
    buzzer=0XFF;
    delay02s();
    buzzer=0X00;
    delay02s();
   }
}

STC89C52 microcontroller uses two timers to control the frequency and output time interval of the buzzer

topic Two timers are used to control the buzzer sound at the same time. Timer 0 controls the frequency, and timer 1 controls the duration of the same frequency. The output is 1, 10, 50, 100, 200, 400, 800, etc. at intervals of 300ms. 1k (hz) square wave. Problems encountered When timer disorder occurs, the priority

51 MCU Programming Buzzer Sounds Happy Birthday

The serial port communication microcontroller controls the buzzer to sound according to the digital data sent by the host computer.

1. Program Function When the host computer sends 1 to the microcontroller, the buzzer sounds at a frequency of 400ms. When 2 is sent, it sounds at a frequency of 200ms. When 3 is sent, it sounds at a frequency of 100ms. When 4 is sent, the buzzer is turned off. 2. Program source code #include reg52.h /
