Laboratoriya ishi №13. Yetti segmentli bitta raqamli ko‘rsatkich. Laboratoriya ishining maqsadi

Laboratoriyaning amaliy qismi.
MAX7219 -dagi 8x8 LED matritsasini Arduinoga ulash
Modelni yig‘ish uchun bizga kerak:

• 
  Arduino UNO R3 x 1 dona.
  
• 
  LED matritsasi 8 × 8 MAX7219 x 1 dona.
  
• 
  DuPont simlari, 2,54 mm, 20 sm x 1 dona.
  

Modelning Arduinoga ulanish sxemasi:

• 
  DIN moduli pinli Arduino pin8
  
• 
  Arduino pin9 modulining CS pinli
  
• 
  CLK pinli Arduino pin10
  
• 
  VCC moduli pinli 5V quvvat manbai (agar bir nechta matritsali modullar mavjud bo‘lsa, Arduino quvvati etarli bo‘lmaydi va modullar tashqi quvvat manbaidan quvvatlanishi kerak bo‘ladi)
  
• 
  GND pinini modulga ulash
  

Ushbu model uchun quyidagi dastur yozishimiz mumkin
