Hi guys, this is a pretty basic question, but I'm just picking up the hobby again after a bit of a hiatus.
I'm working on a project whereby I'm trying to control 48 5x7 dot matrix displays. I'm relatively certain I have the shift register/Darlington array basic concept understood, but I want to double check I've approaching this right with controlling the the 8 Darlington arrays. With my setup, I'm looking to scan 7 rows across all 48 displays simultaneously. If I attempted to individually connect each input pin on the Darlington to an Arduino output, that would take 56 pins alone. Instead, I should be able to wire the appropriate INPUT1's (and 2's, and 3's, etc.) from each array together at a common node to be driven by a single output pin, correct? Is there something I've overlooking or is it really just that easy?
