LED کو جھلملاتے ہوئے — آپ کا پہلا Arduino پروجیکٹ

// Blinking LED — Your First Arduino Project
// Turns an LED on for one second, then off for one second, repeatedly.

const int LED_PIN = 13;  // Pin connected to the LED

void setup() {
  pinMode(LED_PIN, OUTPUT);  // Set pin 13 as an output
}

void loop() {
  digitalWrite(LED_PIN, HIGH);  // Turn LED ON
  delay(1000);                  // Wait 1 second

  digitalWrite(LED_PIN, LOW);   // Turn LED OFF
  delay(1000);                  // Wait 1 second
}

// EXPERIMENT IDEAS:
// - Change delay(1000) to delay(100) for fast blinking
// - Change delay(1000) to delay(2000) for slow blinking
// - Try delay(50) for a strobe effect
// - Use different values for ON and OFF times:
//   delay(200) ON, delay(800) OFF = short flash
//   delay(800) ON, delay(200) OFF = long flash
