Hello to all guys! .. I'm an Italian guy, so I do not speak perfect English .. anyway ..
I have to do a project for school-leaving examination that involves sending a "word" from pc, send "the word" through the wireless modules using XBEE to 'ARDUINO and see this "word" of 5 led matrix. the "word" must flow, such as at airports.
To control the LED matrix I use the max7219:

This is the datasheet.
As a matrix of LEDs, use these:
So, I connect the anode to the SEG Lines. The cathode to DIG LINES, therefore, the SEG LINES columns, and rows to DIG LINES.
I'm not clear how I connect to the max7219 led matrix, can someone please let me explain?
Thank you very much.
