Ok John. I've ordered the PN2222a part (10 of em). I'm trying to figure out which wire goes to which lead on the pn2222a. They are advertised E, B, and C but I don't know what that means.
That's a great choice of a general purpose transistor. The C, B, E are Collector, Base, and Emitter. In John's diagram, the C is at the top of the transistor where the orange wire goes, the B is in the middle where the 1000 ohm resistor goes, and the E is on the bottom of the transistor where the 100 ohm resistor goes.
