Temperature display on Arduino 4-bit 8×8 LED matrix

(Arduino 4位元8×8 LED矩陣上的溫度顯示)

wiring:
MAX7219       Arduino UNO(NANO)
VCC5V    ->            VCC5V
GND         ->            GND
DINdigitaler     ->   PIN D8
CSdigitaler      ->    PIN D9
CLKdigitaler    ->    PIN D10
//
DS18B20
VCC5V             ->    VCC5V
DATAdigitaler  ->   PIN D2
GND            ->         GND

Code to my github repository:

(I created a new code and shared it with everyone on my YouTube. It has been viewed over 600 times. I wrote the code and created a circuit diagram to merge the data in my github repository, and after 3 This week, I checked github and it has been downloaded more than 100 times, but my likes on YouTube are too few, only 7)
I have deleted my github repository, but you have no way to see the information, and it will appear with 404. I think you will be like everyone else, you will not like me 👍 or you will not subscribe to my channel
