Arduino + Max7219 (Fixed)

Hello! I am new to Arduino forums (since this is my first post)! I am not sure where to put this, but this sounded like the right board to me. I am really sorry if this is wrong!

But to the point. I have an error with my Arduino and Max7219. For some reason the LED Matrix is just solid green the whole time. Here is a picture just to show you all whats wrong.

Sorry for the lighting. My camera needed more light to take it.

As you can see there is my dilemma :frowning:
Here is the code I am using and the hardware:
(This is the demo code to test the Max7219 that I used)

//We always have to include the library
#include "LedControl.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.
 */
LedControl lc=LedControl(12,11,10,1);

/* we always wait a bit between updates of the display */
unsigned long delaytime=100;

void setup() {
  /*
   The MAX72XX is in power-saving mode on startup,
   we have to do a wakeup call
   */
  lc.shutdown(0,false);
  /* Set the brightness to a medium values */
  lc.setIntensity(0,8);
  /* and clear the display */
  lc.clearDisplay(0);
}

/*
 This method will display the characters for the
 word "Arduino" one after the other on the matrix. 
 (you need at least 5x7 leds to see the whole chars)
 */
void writeArduinoOnMatrix() {
  /* here is the data for the characters */

LED Matrix:

Max7219:

Also I have an another question:
Why does my LED Matrix only do green when hooked up to Max7219 but does red when directly hooked up to arduino
Found problem to that question.

Sorry for this big post. I just would like to get this fixed so I can put it in my deadmau5 hat :smiley:

EDIT: For people wondering how I fixed it. I rewired the whole thing from square one.
