I'm in the beginning stages of my project (essentially a stopwatch) and I was starting off by getting my base code in place. So far, I just have it light up a new LED in an array of LEDs every second. The issue is that the first two LED's don't light up all that bright. I know it's not the LED's because I've switched them out with ones I know work. So I've tested it in a variety of methods and it seems overwhelmingly positive that it's something Arduino is doing. So my question is as such:
do pins 2 and 3 have a resistor in them that is much higher than others? can they not output the same voltage/current as the other pins? could my Arduino be damaged?
I should note that the LED's DO light up, but not nearly as bright as they should, you can really only see it in low light.
