Maybe I can help you. I have worked with Op-Amops years ago.
Why do you want to use an op-amp?
That device, the LM324 can be used either in a DC aplication or as a n audio amp.
In either case, the normal method is to provide a split rail, + 12 volt and - 12 volt. If you want a bufgfer, you put a reitor from the output back to the invert input. ykou tie another risistor from the other input to grnd. You will get a voltage out of only a few milivolts.
Are you familiar witrh op-amops? The first thing to lern is to use a split ril supply.
Trying to bnias the thing from a singel suppley can drive your ctrazy.
Why did you want to use a LM324?
I have stron opions about op amps, but even so, I might be of some help.
For gbeneral use, the 4558 dual is a good coice. IMO.
But you can make the LM324 work, but it does have a quirk.
