So I'm trying to rig this up the best way possible, but I think I'm getting a bit mixed up about a couple things (I'm pretty new to this stuff). I had a friend tell me that if I cascade the shift registers in this project (595s) I could get away with using a single 10k pullup resistor for the entire…

using Uno to multiplex 200 common-cathode RGB LEDs, not sure about resistors
