Is there any way to include a file only if it exists?
I want to publish a project of mine to github.
But there are some values defined that can change sometimes but are not critical to the projects source code.
For example the number of leds defined at the beginning of the code can change depending on which hardware I am using.
I think it won't look good if the commit for "fixed typo" would include a change for this value.
Another scenario would be a password that should not be exposed in the git repository.
One scenario is where I have sensitive data like passwords in my sketch, but I want to share this sketch with the public (via github).
Another example is a value (amount of leds on a stripe) that changes often, because I am developing on different devices.
But I don't want these changes to be commited to my repository.
This call instantiates (create an object of type FASTLED) and the green part helps configure the library in one way (type of LED strip and pin where it's connected) while the blue parts are arguments you pass to the instance to help set it up
