Arduino Uno R3 Software
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.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:.

Please post your full sketch.If possible, you should always post code directly in the forum thread as text using code tags:. Do an Auto Format ( Tools Auto Format in the Arduino IDE or Ctrl + B in the Arduino Web Editor) on your code. This will make it easier for you to spot bugs and make it easier for us to read. In the Arduino IDE or Arduino Web Editor, click on the window that contains your sketch code. Press 'Ctrl + A'. This will select all the text. Press 'Ctrl + C'.

This will copy the selected text to the clipboard. In a forum reply here, click on the reply field. Click the button on the forum toolbar. This will add the forum's code tags markup to your reply. Press 'Ctrl + V'.
This will the sketch between the code tags. Move the cursor outside of the code tags before you add any additional text to your reply. Repeat the above process if your sketch has multiple tabs.This will make it easy for anyone to look at it, which will increase the likelihood of you getting help.If the sketch is longer than the 9000 characters maximum allowed by the forum, then it's OK to add it as an attachment. After clicking the 'Reply' button, you will see an 'Attachments and other settings' link.When your code requires a library that's not included with the Arduino IDE please post a link (using the chain links icon on the forum toolbar to make it clickable) to where you downloaded that library from or if you installed it using Library Manger ( Sketch Include Library Manage Libraries in the Arduino IDE or Libraries Library Manager in the Arduino Web Editor) then say so and state the full name of the library.
