Mini Running Text Led Dot Matrix Max7219

 Haloo semua apa kabar ? Baik Ya

Assalamualaikum WrWB 

Haloo, Kali ini kita Ada sebuah Project Led Dot Matrik  Untuk Mini Running Text, Bahan Yg di pakai dalam Project ini :

1. Led Dot matrik  4 atau 8 Modul

2. Kabel Jamper

3.Arduino Nano Robotdyn

4.kabel data untuk Arduino type Micro

Langsung Di rangkai sesuai data di bawah ini 

 

#define CLK_PIN           13 Arduino

#define DATA_PIN         11 Arduino

#define CS_PIN              10 Arduino

VCC             To                VCC

GND            To                 GND

Setelah di rangkai buka halama arduino seperti di bawah ini :

1. #include <MD_Parola.h>
2. #include <MD_MAX72xx.h>
3. #include <SPI.h>
4. 
   
5. // set to 1 if we are implementing the user interface pot, switch, etc
6. #define USE_UI_CONTROL 0
7.
