Example program (UNO development board):Click to download

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

void loop(){
  digitalWrite(3,HIGH);
  delay(500);
  digitalWrite(3,LOW);
  delay(500);

}

Example Program (ESP32 Development Board — Based on Python language, cannot be uploaded using Arduino IDE):

import machine
import time


pin2 = machine.Pin(2, machine.Pin.OUT)
while True:
    pin2.value(1)
    time.sleep_ms(500)
    pin2.value(0)
    time.sleep_ms(500)
