İlk olarak ekrana FERHAT harflerini teker teker yazırma işlemi. Kartımız ve segment ledimiz ile yapılan
bir proje. Harfler teker teker led üzerinde yanacak sonra diğer harfe geçecek şekilde
int a=4;int b=5;int c=6;int d=7;int e=8;int f=3;int g=2;void setup(){pinMode(a,OUTPUT);pinMode(b,OUTPUT);pinMode(c,OUTPUT);pinMode(d,OUTPUT);pinMode(e,OUTPUT);pinMode(f,OUTPUT);pinMode(e,OUTPUT);pinMode(g,OUTPUT);}void loop(){digitalWrite(a,LOW);digitalWrite(e,LOW);digitalWrite(f,LOW);digitalWrite(g,LOW);delay(1000);digitalWrite(b,HIGH);digitalWrite(c,HIGH);digitalWrite(d,HIGH);delay(1000);digitalWrite(b,HIGH);digitalWrite(c,HIGH);digitalWrite(d,HIGH);delay(1000);digitalWrite(a,LOW);digitalWrite(e,LOW);digitalWrite(f,LOW);digitalWrite(g,LOW);digitalWrite(d,LOW);delay(1000);digitalWrite(d,HIGH);digitalWrite(b,LOW);digitalWrite(c,LOW);delay(1000);digitalWrite(a,HIGH);delay(1000);digitalWrite(a,LOW);delay(1000);digitalWrite(b,HIGH);digitalWrite(c,HIGH);digitalWrite(g,HIGH);delay(1000);digitalWrite(a,HIGH);digitalWrite(b,HIGH);digitalWrite(c,HIGH);digitalWrite(d,HIGH);digitalWrite(e,HIGH);digitalWrite(f,HIGH);digitalWrite(g,HIGH);delay(4000);}
Proje - 2
Arduino ile çıkarma işlemi yaptığımıda sonucu ekrana yazan projemiz. Sonucun rakamları teker teker ekrana sırasıyla
yazılacaktır.
Çıkarma İşlemi : 1476-12=1464 Yani ledimizde 1464 yazacak sırasıyla
