Hi @geonwoo1234. Please upload this simple test sketch to your Nano ESP32 board:

void setup() {
  pinMode(LED_BUILTIN, OUTPUT);
  pinMode(LED_RED, OUTPUT);
  pinMode(LED_GREEN, OUTPUT);
  pinMode(LED_BLUE, OUTPUT);
}

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

  digitalWrite(LED_RED, LOW);
  delay(500);
  digitalWrite(LED_RED, HIGH);
  delay(500);
  digitalWrite(LED_GREEN, LOW);
  delay(500);
  digitalWrite(LED_GREEN, HIGH);
  delay(500);
  digitalWrite(LED_BLUE, LOW);
  delay(500);
  digitalWrite(LED_BLUE, HIGH);
  delay(500);
}

After uploading that sketch, do you see each of the LEDs blink on and off in turn?
