So I've recently been playing with my first Arduino, until it, for some weird reason, stopped working.
What I did:
I had it attached to a breadboard. When I say attached, I mean it was supplying power to the breadboard. I was messing around with a motor, which wasn't performing very well when using the standard 5v output the Arduino supplies. So, I decided to buy some batteries - 10 AA batteries, to be precise. As I connected my battery back to the other side of my breadboard (there are two power input rows on my breadboard - one on the left and one on the right. (I thought) the Arduino was supplying power to the left input), I had completely forgotten that I had the two power input rows linked together with jumper wires. So I had the Arduino powering both the left and the right side rows of the breadboard. So all of a sudden, when I linked the battery pack to the right side row of my breadboard, my Arduino turned on. I was puzzled. When I finally realized the two power input rows were linked, I slapped myself.
Now, my Arduino turns on, but the code I had on it is no longer executed. And usually, when I turn the Arduino on, the "L" LED blinks twice. Now, it just turns on and stays on. The power outputs still work, as I still have power flowing through my breadboard. The reset button does nothing.
The Arduino IDE also no longer detects my board. Infact, my whole computer doesn't even detect it.
I know it was really stupid of me to supply 14+ volts to it, but I didn't do it intentionally. And, the only reason I used 10 AA batteries was because that's the amount my (only) battery pack required.
What do you guys think? Am I screwed? Is it fried?
