Hi,
I'm been drawing circuits to get my calculations right for having a PIC chip driving 9 LED's. Since I have a number of them I wanted to make sure I had all the right resistors etc in place.
During my research I got quite confused about how the LED's should be connected. Some examples I see are done one way and others another.
I've put together 3 options for connecting an LED to a PIC (see attachment). Firstly can someone check that my assumptions are valid, and secondly which one is the best? Or what questions should I be asking in terms of figuring out which way to do it.
I'm currently doing option 1, and am confused about option 2 (don't know if that's correct) and am thinking I should go to option 3
Many thanks,
Craig
