Ideas For Guitar Parts

The great thing about composing music is that it's a massive learning experience. Where can I dig into learning more about guitar parts? It would be nice to eventually get a strumming pattern going or decode how to do a proper rhythm pattern. I've just been thinking of them as arpeggio's but there must be other things that you can do with them. Out of all the instruments I have the biggest problem with guitar. Just not sure what to do with it. So far all my melody ideas have just been written for piano because of this.

Looking for ideas that you guys have written and notation ideas.

Thank you
