So I learn best by trial and error. I got out the breadboard and a bunch of LEDs. first I setup up about 12 LEDs and a 1k resistor for each (what I have in mass quantities) and connected them in parallel. gave it some power. they werent as bright as they can be but they lit up. next I tried them in series. I believe I was able to get about 4 to light up. I had one 1k resistor on that circuit. then I decided to live dangerous and dropped LEDs all along the voltage and ground rails. 117 leds give or take. connected a 9v with no resistors and they all lit up nice and bright. I don't know what I learned but I like it.
