void setup() {
  lcd.begin(16, 2);
  lcd.print("Subscribe!!");
  delay(1000);
  pinMode(ledPin, OUTPUT);
  lcd.clear();
  lcd.print("Counting to 100...");
}
void loop() {
  for (int count = 1; count <= 100; count++) {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("Count: ");
    lcd.print(count);
    // Blink LED for multiples of 3
    if (count % 3 == 0) {
      digitalWrite(ledPin, HIGH);
      delay(1000);
      digitalWrite(ledPin, LOW);
      ledBlinks++;
    }
    delay(1000); // Wait before next count
  }
  // Display final result
  lcd.clear();
  lcd.print("Done! Count: 100");
  lcd.setCursor(0, 1);
  lcd.print("LED Blinks: ");
  lcd.print(ledBlinks);
  while (true); // Stop after counting
}
