Scrolling text with Arduino Uno and MAX7219 Led Matrix

MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. If you want to connect a few of these cheap led matrixes that are based on MAX7219 to your arduino you are going to need a library such as LedControl or MaxMatrix. For my tests I chose the later one. Check below the code and a video to see it in action.

 

I bought mine from this seller

    I am using 4In1 Module. The above code is not working. The string is scrolling vertically and individually in each of the 4 matrix display.
