says "Connect LED pins 3 and 8 to GND. Use a resistor between each
of the other connections to your Arduino"
I wired it up that way, and of course it works...but just got me thinking:
since its all in series couldn't I just connect pins 3 and 8 to GND using a resistor (for each) as the jumper? Doesn't that effectively do the same thing as the 8 resistors?
also, is it ok to send both pins 3 and and 8 to the GND rail on my breadboard, and then jump that to GND using only 1 resistor?
I thought that when wiring in series, you can put the resistor wherever you want and it effects the whole circuit?
