Arduino UNO – Potansiyometre ile 10 LED’li Seviye Göstergesi

Bu çalışmamızda potansiyometrenin değerini 0’dan 5 Volta kadar değiştireceğiz ve bu değişimi 10 LED ile göstereceğiz.

Yukarıdaki devrede yerden kazanmak için LED’lerin bacaklarının boylarını değiştirdim. Uzun bacak ‘Anot’ kısa bacak ‘Katot’ olarak kullanılmıştır.

      olmadığını kontrol ettik.
