Midterm prep

At present, we haven't figured out what to do. It may be that the music is triggered and the LED will follow, or a random game, or a reminder device will send a reminder when it receives a certain signal. I think each item is very interesting, so I am still considering it. Of course, I will also imagine what needs to be set and used in the process. Because it is the first independent project, I think I may choose a relatively simple one.
