Hola a todos,por favor alguien que me pueda decir como cambiar el letrero del srrol es decir que vaya todo corrido y no de saltos,tengo 4 leds y si la palabra no cabe entera va dando saltos intermitentes hasta que se ve,yo quiero que se lea (cerramos los lunes) todo seguido.

Gracias.

//We always have to include the library
#include "LedControlMS.h"

 Now we need a LedControl to work with.
 ***** These pin numbers will probably not work with your hardware *****
 pin 12 is connected to the DataIn 
 pin 11 is connected to the CLK 
 pin 10 is connected to LOAD 
 We have only a single MAX72XX.
