Need advice on power setup for 88 MegaBrites over a large area

Using Arduino Project Guidance
6

Thanks for the reply macegr,

I hadn't thought of that limitation. Is it just too much noise developing over that distance in TTL that's the problem?

Also, could I not just use 1 arduino for the whole setup with octobars? 1 data pin for each set of 3 octobars (4 data pins total) and all sets sharing the same latch, clock, and enable pin?

Thanks!
