Quiz 1
Assignment 1
How to properly Reinstall Arduino IDE to avoid Compilation & Library Errors?1:13
If you are facing constant compilation errors, or “Multiple Library Detected” errors, It will be only fixable by reinstalling the Arduino IDE. Sadly, Just uninstalling Arduino IDE. using the official uninstaller tool won't remove the board packages and libraries that are present in another directory. Thus even if you install a new version, old broken packages will be present.
