I am going to make the led matrix circuit on the Arduino playground here http://arduino.cc/playground/Main/DirectDriveLEDMatrix
I am going to make it in to a 8x8 led matrix table with high power led's if I did this would I need transistors if so how would I arrange them. the led's I am going to use have a forward current of 35ma and a forward voltage of 3.4v
