MALZEME LİSTESİ:

1. 512 adet led
2. 9 tane 74HC575 Entegre – Bunlar shift register entegreler.
3. 16 adet PN2222 transistör
4. 64 adet 220 ohm direnç
5. TS – 1109 buton
6. Arduino UNO
7. 5V  2A güç kaynağı

AÇIKLAMA :

shift register denen entegreleri kullanıyoruz. Yani şöyle ki, bir ana entegremiz var. Bu ana entegremiz adres seçimlerini, zamanlamaları ve açıp kapatmaları ayarlıyor. Sonra 8 tane de shift register entegresi takıyoruz, bu entegreler de 8’li bir kümeden istediğimizi açıp kapatıyor; bu sayede de her bir ledi ayrı ayrı kontrol edebiliyoruz.
