Here is the code for its on board LED blinking.

// ESP32 LED Blinking Example

// This code blinks the built-in LED (pin 2) on an ESP32 board.

void setup() {

  // Set the LED pin as an OUTPUT

  pinMode(2, OUTPUT);

}

void loop() {

  // Turn the LED on

  digitalWrite(2, HIGH);

  delay(1000); // Wait for 1 second

  // Turn the LED off

  digitalWrite(2, LOW);

  delay(1000); // Wait for 1 second

}

Here is the code for SD Card.
