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 :
- #include <MD_Parola.h>
- #include <MD_MAX72xx.h>
- #include <SPI.h>
- // set to 1 if we are implementing the user interface pot, switch, etc
- #define USE_UI_CONTROL 0
- #if USE_UI_CONTROL

- // Turn on debug statements to the serial output
- #define DEBUG 0
- #if DEBUG
