Hi everyone .
I have been trying for some time to create an alarm clock combined with a reader ( with infinite loop function) to listen to white noise for the duration of the night in the room.
you can understand that the reader must switch off at a pre-established time to make room for the alarm clock which must sound at a specific time.
the only simple way I've found to do it, is to use an ipad alarm clock and a bluetooth app that puts the cd or dvd player in standby through a relay.
there are many products on the net but I can't find the right one that works with the programmed time, do you know the bluetooth app and pcb relay?
