Hey I have had great successes here with a few projects of mine, thanks to everyone's help. I am starting to standardize my LED signage project to a point where I want to make one card that will apply to many many signs. I want it to be able to drive ~200 LED's. Instead of a text scroller I have different "Zones" but it still operates under the principle of an LED Matrix. I have seen a few circuits and am looking for the one that resonates as one of the better, more reliable circuits.
I am thinking along the lines of a series of 74HC595's and a MCU, I also want to have PWM control of the LED intensity. Can you think of a successful project example I could use to cut my teeth on? I am trying to roll something out pretty soon, so I'd rather hear some testimony of which one to use as opposed to ordering the wrong parts 2 or 3 times.
Cheers,
Keny
