I need some help. I have an Anrduino Uno lots of resistors protoboard power supply and the thing that causing my a headache 
a 8x8 Bicolour Matrix.
I've looked for examples on how to drive this but I want to be able to use some Arduino pins for other things, like switchs, sensors etc. Problem is I've looked at some guides on using 74HC595 or MAX7219 but all show sing a matrix that's common Cathode.
The Matrix I have is a Common Anode? So how do I hook this up to an Arduino and a LED Driver/Shift Register (Or what chip can I use)
Hope someone can help
Neil
