i have some common anode displays that i don't want to waste. I have read how to wire the common anode to the opposite side on the matrix. Will it still work with the tutorial on this site?

No. MAX7219 needs common-cathode. You could use TLC5940 instead: http://tronixstuff.com/2013/10/21/tutorial-arduino-tlc5940-led-driver-ic/ __________________ - Helping you make it with great value for supported hobbyist electronics from adafruit, Altronics, DFRobot, Freetronics, Pololu and more! - Support always available for our products - email support@tronixlabs.com
