How do I clear space from my Arduino Uno?

It's not allowing me to upload any more codes, so is there any way to clear what is already in it or to just reset it?

Every time you upload the previous program is cleared.

Please do this:

  • File > Preferences > Show verbose output during: > compilation (uncheck) > upload (check) > OK
  • Sketch > Upload
  • After the process fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).

If you clear out space, don't things get really cluttered?
