Hello All,

I am REALLY green when it comes to this stuff but after a few successful builds and uploads I tried uploading another version of a sketch and it would come back with an error message. I disconnected all wires and tried to upload "Blink" and the same error came back. I am not sure what went wrong. I have copied and pasted the error message below. Thank you all for your help.

Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino Uno"

Sketch uses 928 bytes (2%) of program storage space. Maximum is 32256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

avrdude done. Thank you.

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

Any and all suggestions or opinions are appreciated. The board did just pass the loopback test. IDK if that matters or not

After trials and research I just purchased another Uno.
