7 segment displayle dijital çıkış uygulaması yapmak

by admin
on Eylül 27, 2023

Görselde ortak katotlu ve ortak anotlu 7 segment displayin yapısı, Görsel 2.25b’de ise dijital çıkış şeması ve devresi görülmektedir. Displayin a, b, c, d, e, f, g segmentleri sırasıyla
Arduino’nun 6, 5, 4, 3, 2, 1, 0 numaralı pinlerine bağlıdır. Ortak katot Arduino’nun GND ucuna
bağlıdır. Karar yapısı olarak switch case kullanılmıştır. Rakam değişkenin içeriğine göre ilgili komut kümesi çalıştırılarak dijital çıkışların durumuna göre rakamlar displayde yanmaktadır. For
döngüsüyle 0,2 saniyede bir rakamlar artırılmaktadır. Tabloda ortak katot display giriş kodları verilmiştir.
