When you see a "No such file or directory" error it almost always means you need to install the library that contains the missing file.

Often the code you're compiling will come with documentation (either a comment or separate document) that tells you where to get the library dependencies.

Note that libraries may have dependencies on other libraries.

In other cases the author of the code will not have been so kind and you'll need to go on a hunt for the missing library.

A good place to start is the Arduino IDE's Library Manager:

  • Sketch > Include Library > Manage Libraries...
  • In the "Filter your search..." box, type some keywords you have gleaned from the missing file name.
  • Scroll through the results for the right library. Click on it.
  • Click "Install".
  • Wait for installation to finish.
  • Click "Close".
  • Try compiling your code again.

If you have no luck in Library Manager then load up your favorite search engine and do a search for the missing filename. You will often get multiple results. If you have a lot of results you might add "arduino" as an additional search keyword. I will usually prefer results on github.com since that is where most Arduino libraries are hosted and downloading from there is fast and easy. In some cases there will be multiple libraries that contain the given filename and you'll need to do some evaluation to determine which seems the most appropriate, then try it out. After downloading the library you found you'll need to install it. This requires a different process than the Library Manager installation. You will find instructions here:

Hi,
Welcome to the forum.

Please read http://forum.arduino.cc/index.php/topic,148850.0.html.
Then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

Did you write the code?
If not can you post link to where you got it please?

Thanks.. Tom... :slight_smile:
