i tried to plug the led to 5v (with a resistor) and ground and that didnt work either(on the analog side).
That's curious. Are you sure you aren't testing it with a blown LED? What resistor value are you using?
The other reason i wired weird is i dont like how negative is on the left side of my breadboard and positive is on the other side, i didnt know it mattered which way breadboards are used, thats why i did it whichever.
There should be two rails on each side of the board, conventionally used for power and ground. Some solderless breadboards boards are printed to make it clear which pins are connected internally, but yours doesn't seem to be. You need to be clear how they're connected internally, and at the moment you aren't, judging by the way you connected the circuit in that picture. This wikipedia article about breadboards
describes it and has pictures of the connections which should make things much clearer for you.
i have an arduino uno..
If it's a recent UNO then the microcontroller is a chip mounted in a socket and can be replaced for a fraction of the cost of the whole board, if worst comes to worst and it has been ruined. Your comment that the onboard LED works gives me hope that the damage may not be as bad as it seems, though.
