mp3 player with timer

Heres the thing:
I have developped a mp3 player with a tutorial, and now I need it to mute when it comes a certain time like 23pm and then unmute at 10am for example.
I am a really noob at this and need real help to get this done, its for a christmas family project :stuck_out_tongue:

I have attached all the files needed, the project and folders like I use them.

The real idea is to set an hour to mute the sound and another to unmute it.

I really hope you guys can help me ! :S
Its ok to change all the code and use it for your purposes, I don’t mind :smiley:
thanks in advance:thumb2:
