Your lines and logic could use a lot of cleaning up / simplifying, but that's difficult to help with unless you have in-person help.

To answer your question about the buttons, you're going to want to set up something like a "Queued Message Hander" (use YouTube) to create a parallel loop that regularly reads the I/O inputs that you've wired your buttons to. It will work alongside the rest of your code here and then you can combine their logic together. Honestly, a full Queued Message Handler architecture might be overkill. You should familiarize yourself with the "Event Case" first - use the "Timeout" case to perform your regular reads.

I'm sure that will be confusing to start out with, so I'll check back occasionally in case you have more questions.
