I have a LM324 Op-Amp, but to be honest, I have no idea how to use it...I understand a moderate amount about electronics, with the exception of reading schematics, but this project I'm making sounds simple enough. I just want to make a little amplifier for my speakers, so it can be a bit louder, I plan on using a few(or a lot) of 1.5v button batteries. Anyways, I got no idea how to use my LM324, I understand that 1in- and 1in+ yields a 1out, but my speakers have a + and - inputs, so how do I make that work?Also, the ground wire goes...where( a piece of plastic?)?
