hello, I tried making a l293d 4wd Arduino Uno obstacle avoider,
it worked the first time but when I decided to switch the motor connections then my 16v battery accidentaly touched one of the motor connection terminals then it suddenly stopped working!
nothing is moving. I tried uploading again but it didn’t work it takes a long time to upload then gives me this error message:

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with

option enabled in File → Preferences.
I got all the wiring details and code from here:
