Avrdude problem while uploading to arduino nano

Today I used ARDUINO IDE for coding my new projects from morning till now,
After some hours of coding and test code uploaded to Arduino nano, my projects were complete and I try to upload it to my Arduino nano (the full code, not test code), then I started my car engine so I'm can test the projects directly,but when I come to my laptop again its throws some errors at me

this is the code that ARDUINO IDE give to me :

Arduino: 1.8.9, Board: "Arduino Nano, ATmega328P"

Sketch uses 6626 bytes (21%) of program storage space. Maximum is 30720 bytes.
Global variables use 587 bytes (28%) of dynamic memory, leaving 1461 bytes for local variables. Maximum is 2048 bytes.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

The Arduino fixed itself after I connect the 5v pin to a 6v battery for 1 sec, then plugged it in back to my laptop and re-upload the code it's working again YEY, now I have D.I.Y distance measuring in my cars :slight_smile:

why is nobody want to help me during the error? avrdude is hard to fix?

There are many different possible causes of this particular error so it's very hard to diagnose remotely. For this reason, we don't always provide as much support for these upload errors as the people experiencing them might wish. I was following the thread and had it on my list of things to look at when I had more time, but you already got it working on your own!
