[sdiy] neophyte question - 9 volt battery to CV control

[ahlist]

Hi,

I'm new to all this. In my inexperience, I envision something like the
following:

a 9 volt battery attached to some resistors(?) to take down the
voltage attached to a potentiometer attached to a CV input.

Would something like this work?

The end goal would be to use similar analog outputs from a
micro-controller to the CV input.

All advice and education appreciated.
