The following is the eroor shown by the IDE

exit status 3
Error compiling for board Arduino/Genuino Uno.

Please Help

There is almost certainly more information in the error message.

The message says there is a compiling problem, not an uploading problem. Post the program you are trying to compile.

Have you ever been able to upload any program to your Uno?

What operating system are you using on your PC?
