Hi, I maybe broken my Uno. Idk, When I connect three led, and let them lights, first lights normally(2V) and the other just a veryveryveryvery bit(1,7V). Do I need to change chip, or what? Thanks.


Sounds like the results you would get if you left out a 'pinMode(pin, OUTPUT)' somewhere.

What size resistor are you using?

You probably didn't set the pins to output.

I'm using 220ohm resistor, but I am absolutely dumbass and I forgot "output" code.
