Hi, I apologize in advance for not knowing the right terminology, I've been on wikipedia for the last two hours and my brain is mush. I'm trying to design a basic circuit that will cycle through multiple circuits in series. I really have no idea how to describe this, except to draw it. I know my schematic is awful, and I don't know how accurate my transistor symbols are, but I hope the gist is evident. I need a current to turn on the load at A, then when A is manually turned off by a switch, bypass it and turn on B, until B is turned off, then C switches on, ad infinitum. The only way I could think of to do this was to use transistors to force current to the load, since it will have a higher resistance than the bypass will. I know I need some sort of counter or memory circuit to do this, unless there's a much easier way that I don't understand. I'm decently skilled with soldering, so I'll be building this myself, but I need help designing and then picking out low cost components. Thanks in advance!
