Error compiling for board Arduino Uno

OK, that is the reason why the IDE's user interface didn't match what I described in the instructions. The Arduino IDE 1.x Boards Manager has a slightly different design.

You can't uninstall the "Arduino AVR Boards" platform when using Arduino IDE 1.x, but I think we can accomplish the same fixr by installing an older version and then updating back to the latest version again. I'll provide instructions you can follow to do that:

  1. Select Tools > Board > Boards Manager... from the Arduino IDE menus.
    The "Boards Manager" dialog will open.
  2. Wait for the updates to finish, as shown by the messages printed at the bottom of the "Boards Manager" dialog.
  3. Scroll down through the list of boards platforms until you find the "Arduino AVR Boards" entry. Click on it.
    A "Select version" dropdown will appear in the entry.
  4. Click on the "Select version" dropdown.
    It will expand.
  5. Select "1.8.3" from the menu.
  6. Click the "Install" button in the "Arduino AVR Boards" entry.
  7. Wait for the installation to finish.
  8. Click on the " Arduino AVR Boards" entry. Click on it.
    Some buttons will appear on the entry.
  9. Click the "Update" button on the "Arduino AVR Boards" entry.
  10. Wait for the update to finish.
  11. Click the "Close" button on the "Boards Manager" dialog.
    The "Boards Manager" dialog will close.
