5 of Arduino IDE example program

Arduino UNO Example (for Mixly IDE, Arduino IDE):

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);
  }

}

ESP32 Python Example (for Mixly IDE / Micskit)
(Choose the Python ESP32 [ESP32 Generic(4MB)] to switch to code mode upload):

import machine


pin4 = machine.Pin(4, machine.Pin.IN)
pin12 = machine.Pin(12, machine.Pin.OUT)
while True:
    if pin4.value() == 1:
        pin12.value(1)
    else:
        pin12.value(0)
