Dipshit here (this guy >>2391025).

I have a 10 to 4 BCD input that I built with diodes, but the signals are 12v and I cannot let 12v touch an arduino so I'm using an opto-coupler to keep the arduino safe(ish). But how the fuck do I actually get the signals from the opto-coupler to the arduino? I have two configurations but everyone online is only mentioning B, but I would rather want to do A because that would really clean up my code.

What do? I can post more info if needed.
