First place to look for Arduino libraries is on the Arduino site that may just send you to
Github 
But really this post is to tell the OP that in future, look on the same site that this forum is on.
There's the standard libraries through a link on the main reference page.
There's the official libraries and many user-contributed ones on the Libraries pages.
There's other code and libraries in The Playground on this site.
Another smart thing to do is look on the first pages of the different forum sections where what you want may have already been solved. If you have definite terms then thry them in the search engine.
Why, when you can just ask? Because looking things up is quicker as saves everyone a lot of typing!
