Digital volume control sleep timer

Hi.

I would like some opinions on this idea.

Bassically, if listening to music when trying to get to sleep, when the music stops I wake up again. Very annoying.

So, my plan is to use a digital volume control IC (Like the one used here https://electronic-circuits-diagrams.com/audioimages/audiockt11.shtml), and to have a pulse generator to represent someone pressing the switch, and it would do this, wait a while, then give out another pulse, wait, etc, so that the volume would be lowered slowly - albeit in stages - preventing a sudden loss of volume. If it works well, I may add a circuit that will turn off all equipment (hi-fi etc) after the volume had been lowered to zero.

Obviously, a timer of some description would be required so that the music was alowed to play for a certain ammount of time, before it started to lower the volume.

Doesn't sound to complicated, I just wondered if anyone had done any thing like this before, or had any suggestions?

Cheers,

Tim

A pic would be a simple way to do it... wait a minute, beginning to sound like Nigel :lol:

How about a 555 timer giving a pulse every X seconds ?
