I built a 5x5 matrix, multiplexed, using an UNO v.3.0 that runs with music sync from A0 or a timer running frames, and it works fine.
I bought several Nano 328 boards, tested them on various lighting rigs and sketches I have laying around, but they won’t run my matrix, at all.
I have tested my electronic connections and my sketches are all simple and work with my UNO and will load to my Nanos, but I get no voltage out of the digital pins, I’m getting lost here, Help?
Here’s the link to my project, as done by the originator, Lincomatic
Thanks in advance, this stuff is fantastic,
