Hello all,
I drew a quick visual to help everyone out who is new. I am new myself as in I just found this project today. So I am not 100 percent sure if it's correct but it looks right from what I can tell. If you look at the source code for the LED driver board
//*****
int data = 9;
int strob = 8;
int clock = 10;
int oe = 11;
int count = 0;
int dato = 0;
//******
the INT = X correlates with the number on the Arduino board. Once you see this, everything else seems to fall into place. Take a look at the images below. I hope this helps. Also inorder to daisy chain more 4794 LED driver boards, Pin 9 and Pin 10 look like the pins to connect to the next 4794 LED Driver as showen in the Datashate

**Also note, I turned the Arduino Diagram upside down in the diagram to better suit the way the picture was taken. **
take care
