I am wanting to make a Digital volume control that does not require amplification. i basically want to use it with 3.5mm audio jack in, and 3.5mm audio jack out, with the ability to fade the volume down via digital push button until no audio can pass through, and then obviously have the ability to fade the volume back up again via another digital push button.
The simplest thing I have found so far is to use a DS1802 potentiometer but am unsure of a couple of parts used in the image circled (apart from the 5v regulator.

Also If anybody knows of a simpler/cheaper way to make a digital button volume control i would love to hear it.
Thank you so much.
The small black 3 pin part and the capacitor are the parts i am unsure of as this is not an item i have on hand but is an item i am wanting to make.
The only place i could find an example of how to make a simple digital volume controller was on this website: **broken link removed**
This is where i got the image from.
