Just to make sure I am heading in the right direction:
To have enough outputs on an Arduino Duemilanove to drive a 4x4 Matrix of LED's independently I would need an LED Driver such as a Maxim MAX7219 correct?
I want to make an electronic 4x4 Reversi/Othello game, which means I would need the 4x4 to be able to drive 2 different colors (and off), and 4x4 matrix of switches. The switches are pretty simple as only one gets accessed at a time so I don't have to worry about ghosting inputs.
But to get the LEDs to light correctly without lighting up ones I do not want lit, and without a slow blinking / pulsing as it goes through the columns, I'd have to use something similar to that kind of driver?
All 16 LED's need to be controlled independently in 3 states: color1, color2, and off. Without a driver (which I would need something similar to address the power issue) I don't see how I could do all this with the Duemilanove's number of outputs.
Just want to make sure I am heading in the right direction. Thoughts?
EDIT: Half my hassle would be relieved by just going with the mega it seems . . . To bad.
