I can't decide which forum this thread should go in: Display or Audio. I chose Display.
I have had an iDuino (brand unknown) for a while, and have been enjoying it. It shipped with an ATMEGA128 attached, but I bought and swapped in a 328, because I thought it was faster. More recently, I bought an Arduino Uno, a breadboard, a 4-pack of 1 KHohm and 470 Ohm resistors, and some jumpers. I put some of the parts together, following https://www.youtube.com/watch?v=DT9K0ZZl_rQ's guide, and I got TV output working! Now, for my project, I need audio (it's a gaming console), and I have read that 1 microprocessor alone could not output video and audio. Could I somehow combine my Arduino Uno (with it's ATMEGA 328) and the old ATMEGA 128 to make audio and video work together?
