I'm having trouble with the coding for putting all of this together. Right now, I can independently set up all of these. I can make a piezo buzz to jingle bells. I can make red and green lights blink on and off. I can make an LCD screen put the lyrics to jingle bells in succession. However, I cannot find a way to put this together into one unified, working system. The main issue I am coming across is the coding for it. Any help would be appreciated!
Check out this fantastic post stickied at the top of this section:

That helped me out a lot with being able to run multiple "processes" at once on my projects.
Thanks!
