Here's a new plan, I will use more than one Arduino for the machine. The DMD display I will make myself, I know that its 4096 hand soldered LED's but I want this to be a really homemade machine. Also by soldering this it gives me bragging rights, over my friends. Will the UNO be sufficient. I would like to set it so I can use bitmap for animation. Also how can I make the arduinos communicate, eg. The arduino managing the scoring can send the numbers to the display manager which will convert it to the Bitmap which will display. Also it will send the score and relevant switch triggering to the sound arduino that will trigger the relevant clips. Will the DMD arduino be able to handle the 512 shift registers? Is there another option to handle the DMD.
