Trivial Transistor Circuit
here's a trivial transistor circuit I finally got working just to convince myself (a) I understand transistors correctly, and (b) I can understand the !@#$ing relationship between abstract transistor terminals and where they actually are in the real world correctly. (Answer: I can only do so after like six tries, apparently. I keep thinking Base should be between Collector and Emitter on the package, and I constantly confuse Collector with Emitter) Stupidly basic thing to accomplish, but still feels fun. I can verify that the PNP bipolar transistor does in fact conduct from emitter to collector when I pull the base low, and doesn't when I pull it high.

Also been playing around with a little DC motor. I have a stepper motor in my possession, but I think I need to hook up some more parts before I can drive it correctly.
