Example program (UNO development board):

void setup(){
  Serial.begin(9600);
  pinMode(4, INPUT);
  pinMode(9, OUTPUT);
}

void loop(){
  //有源蜂鸣器模块接UNO开发板D9，电导开关模块接UNO开发板D4；
  //电导开关模块在连接到导体时，会产生一个高电平（1），使蜂鸣器响起；
  //当未检测到导体连接时，蜂鸣器不响。
  if (digitalRead(4) == 1) {
    digitalWrite(9,HIGH);
    Serial.println(String("导体连接：") + String(digitalRead(4)));

  } else if (digitalRead(4) == 0) {
    Serial.println(String("断开：") + String(digitalRead(4)));
    digitalWrite(9,LOW);
  }

}

10, Test results

Arduino UNO test results:

After the device is connected and the program is uploaded to the Arduino UNO development board, you will find that the buzzer sounds when the conductivity switch module is connected to the conductor; otherwise, the buzzer does not sound.
