5 of Arduino IDE example program

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

void setup(){
  pinMode(2, INPUT);
  pinMode(3, OUTPUT);
}

void loop(){
  if (digitalRead(2) == LOW) {
    digitalWrite(3,HIGH);

  } else {
    digitalWrite(3,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() == 0:
        pin12.value(0)
    else:
        pin12.value(1)
