I have an Arduino UNO with Arduino IDE installed in Ubuntu 16.04, It worked fine, but once I was working with a 12v circuit and the Arduino moved (without power) to the circuit... I saw that the board turn on some LEDs (I didn't see specific ones), seeing that I moved the Arduino to a safer place... I didn't see anything burned or smell something... But after that, I tried a lot of times to Upload the code and the AVRDUDE: programmer is not responding presents! I looked in Forums and Google, I tried the reset button and unplug the arduino and what have you but none of them worked...
Here is the output:

Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.
