8-mavzu: 74HC595 suruvchi registr mikrosxemasi. 4 razryadli matrisani boshqarish.

Ishdan maqsad: 74HC595 suruvchi registr mikrosxemasini o’rganish va ardunio muhutida dasturini tuzush.

Nazariy ma’lumot

Arduinoda kontrolleridan foydalanishda ko'proq chiqish (pin)lari kerak bo'ladi, bunday holda, eng oson yo'li 74HC595 registrdan foydalanishdir.

74HC595 - sakkiz-bitli ketma-ket, yoki parallel ravishda chiqish amallari va uch holatli chiqishi bilan almashtirish registridir.

Proteusda sxemani yig’ish uchun bizga quyudagi elementlar kerak bo’ladi:

1. 
   Arduino uno
   
2. 
   74HC595 registr
   
3. 
   Power
   
4. 
   Graund
   
5. 
   Res
   
6. 
   Led
   

1-rasm. Proteus muhutida yig’ilgan holati.



2-rasm. Proteus muhutida ishlagan holati.
