Arduino UNO – 7 Segment Display Kullanımı

on tarafındanYorum bırakın

7 Segment Display tek bir rakamı gösterir. Rakamları gösterebilmek için 7 adet LED kullanır. Diğer bir 8. LED ise noktadır. Ondalıklı sayıları gösterecek şekilde bir kaç tane kullanılması gerekiyorsa ondalık kısmın noktası olarak kullanılmaktadır. Yapısı şekildeki gibidir.

Arduino UNO ve Ortak Anot 7 Segment Display Devresi

Bu devrede ortak uç Vcc’ye yani 5V’a takılır. Böylece LED’lere (+) verilmiş olur. Geriye kalan (-) uç yani GND dijital pinlerden sağlanır. Hangi dijital pin LOW (yani eksi veya GND veya Toprak veya DÜŞÜK) yapılırsa o pine bağlı LED yanacaktır. HIGH yapılan pinlerdeki LED’ler de söneceklerdir.
