ARDUINO Code:
int textSpeed = 50;
int text = “WELCOME TO THE Z-HUT”;
#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include <SPI.h>
#define MAX_DEVICES 4
#define CLK_PIN 13
#define DATA_PIN 11
#define CS_PIN 10
MD_Parola P = MD_Parola(CS_PIN, MAX_DEVICES);
const uint8_t DIRECTION_SET = 8; // change the effect
const uint8_t INVERT_SET = 9; // change the invert
uint8_t scrollSpeed = textSpeed;
textEffect_t scrollEffect = PA_SCROLL_LEFT;
textPosition_t scrollAlign = PA_LEFT;
uint16_t scrollPause = 10; // in milliseconds
#define BUF_SIZE 300
void setup()

}
