I picked up my Arduino after taking a break from it for awhile. I tried a python -> ardunio communication sketch and fount it ran oddly. (I'd have to run the script twice to get it to work, and after it said 'LED lit' the LED remained dark.) I loaded the basic blink sketch and put an LED on 13 and GND. It didn't work, nor did 3 other LEDs. I tried using other pins, but that isn't working either. Using the Blink sketch, the pin voltage hovers around from ~.112 to ~.130.
Did I fry my Ardunio somehow?

Re: Sketches running oddly or not working
It is better to use a current limiting resistor in series with the led. I know there are a lot of examples out there that don't, but it is a bad practice. It is possible to damage either the led or the output pin.put an LED on 13 and GND.

You must have some working pins (pins 0 and 1) if you are able to upload to the Arduino. Do you see led activity when you boot and/or upload to the board?
