Gösterge Kullanımı

7 Segment Display Kullanımı

    Amacımız Arduino ya yüklediğimiz  program ile 0 dan 9 a kadar saymaktır.

Gerekli olan malzemelerimiz:

• 1 X Arduıno
• 1 X Anot Display
• 1 X Breadboard
• 1 X 220ohm direnç

     İlk olarak resimde görüldüğü gibi devremizi kuruyoruz.

 Kodumuz ise;

  pinMode(g, OUTPUT);

  pinMode(dot, OUTPUT);

  digitalWrite(dot,LOW);

}
