I am building a speaker out of two halmark music cards and i wanted to use a potentiometer to control the volume so i wouldn't have to do it on my ipod. I have build one before but did not use a potentiometer so i dont know how to wire it in. Other than the speaker im working on now and the speaker that I built before I have never built anything that involves electronics. What I need help with is what potentiometer I should get and how i should wire it into my project. Mostly I need to know how to wire it but if you could tell me what kind to get that would be great. I search high and low for about and hour but I could not find anything. I have included a diagram of all of the other speaker wiring. If you notice any problems with that also please tell me because i am sort of a noob at this. (I got a soldering iron two days ago) Thanks for the help.
