Membuat internal LED ESP32 berkedip (blinking)

Proyek kali ini kita akan coba membuat LED internal ESP32 berkedip (blinking) berdasarkan interval waktu yang akan kita set dalam script di Arduino IDE.

weekly project 01 - EL5057 Sensing System.

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.
*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
