Grumpy_Mike:
Ok, I looked at charlieplxing, but I dont see how that will help me, I am drawing 0.32Amps for each LED Matrix,
The point about a matrix is that you don't have all the LEDs on at the same time, you multiplex them so fast they look like they are on at the same time.
Otherwise you need drivers to provide the current both sourcing and sinking. This will allow you to control a whole row at a time.
You can not have full none multiplexed controll of each LED in a matrix. Tha act of wiring them up in a matrix means you have to multiplex them.
Ohhh I understand what you are getting at now, so I have decided to go with making it a multiplexed matrix, as this will allow me to have full control over the project. I have changed my LED use down to 54 LED's instead of 96 as I dont want to use all the pins on the arduino. I have created a sketch up of how it would look cuircut wise in a program called yenka. In the sketchup instead of pins from the arduino I used switches to test how it would work following this: http://www.youtube.com/watch?v=-1UPPHjR0vk (Part 1 and 2). The only confusion I am having now is why are the transistors turning on even when there is no current flowing from the collector, I set it up so you turn on 3 Pins and it flows, but then I have random LED's turning on with no connection...
P.S: Im using NPN Transistors
I also need to figure out how to fade the LEDs Off and on, I dont see how in the way I set up multiplexing, as the LED's are constantly flashing on and off.
Anyway here is the pic (NOT COMPLETE PICTURE DO NOT USE):

After Switches Go On:
According to the video only the first switch should go on...
