mavzu: 74HC595 suruvchi registr mikrosxemasi razryadli matrisani boshqarish. Ishdan maqsad

8-mavzu: 74HC595 suruvchi registr mikrosxemasi. 4 razryadli matrisani boshqarish.
Ishdan maqsad: 74HC595 suruvchi registr mikrosxemasini o’rganish va ardunio muhutida dasturini tuzush.

1-rasm. Arduino muhutida dastur yozilgan holat
2-rasm. Proteus muhutida yig’ilgan holati.
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
