Wiring:
Connect LED positive (long leg) to GPIO 2 (you can change the pin number in the code).
Connect LED negative (short leg) to a 220Ω resistor, then to GND.
 
Codes
 
// Define the LED pin
#define LED_PIN 2  // You can use any GPIO pin, GPIO 2 is onboard LED for many ESP32 boards
void setup() {
  // Initialize the LED pin as output
  pinMode(LED_PIN, OUTPUT);
}
void loop() {
  digitalWrite(LED_PIN, HIGH); // Turn LED ON
  delay(1000);                 // Wait for 1 second
  digitalWrite(LED_PIN, LOW);  // Turn LED OFF
  delay(1000);                 // Wait for 1 second
}
