Using Bluetooth to change variables.


I have a functioning program that is controlled by adjusting variables. Is it possible for me to make an app, and adjust the variables through the app? I'm not trying to send any inputs to turn anything on directly, I am trying to just change variables so I can control how long an LED stays on. If that doesn't make sense, please let me know.

Please do not cross post the same question in multiple sections. It wastes our time and resources if we are answering things that are already answered on the other thread.

Sorry, I thought this would be the better category to post the question in. I am not sure how to delete a current thread. I will refrain from that in the future. I believe my other thread has been deleted.

I deleted the post in Programming Questions because the post was identical and wasn't a programming question.
