Having issues using an Arduino to emulate a shift register. Details inside.

Just wanted to give you an update. I plugged your code in. It's sending data out now, but something is off as it's not stable, the data it sends out. A timing issue? Or something. Not surprising considering you're stabbing in the dark since you've not got the hardware to interface it to like I do.

I think I can get it working though. I'm at least 45% confident I can. I think I'll pull the code apart and break it down to as simple of a setup as I can get it. So it just sends out a string of predefined-bits, and does nothing else. Then from there I can build up the rest of the functions it needs.
