Hello! Completely new to Arduino; working on building a cornhole-type game that keeps score and triggers a sound when the bean bag passes through the hole.
I've got IR Break Beam sensors set up and have managed to code the scoring system.
Having trouble triggering a file to play from an SD card though. I know that the set-up and speaker are working, as I've been able to get a sound to play using some simple sample code from the web. But when I try to integrate that into my existing code, I come up short.
Appreciate any insights from this group - I'm sure it answer will jump out at someone here!
Thanks in advance.
