Hi, I'm trying to figure out working with shift registers. I bought a couple of 74HCT4094's, hooked them up through my breadboard to a small matrix with some LEDs and my Arduino. Without multiplexing everything works fine, but no matter what circuit I build (changing wires, resistors, transistors, ...
