😊 ماموریت ۸۱: شکلک روی ماتریس ۸×۸

سیم‌کشی

1. Arduino Uno (VCC5) ⟷ LED Matrix 8×8 (MAX7219) (VCC)
2. LED Matrix 8×8 (MAX7219) (GND) ⟷ Arduino Uno (GND1)
3. Arduino Uno (D12) ⟷ LED Matrix 8×8 (MAX7219) (DIN)
4. Arduino Uno (D10) ⟷ LED Matrix 8×8 (MAX7219) (CS)
5. Arduino Uno (D11) ⟷ LED Matrix 8×8 (MAX7219) (CLK)
