I need a little advice on an electronics project that I'm working on.

It's really simple. I just want to make a basic device that takes the 12v DC from a car battery, reduce it to 5v and be able to adjust the voltage between 0 and 5v. My goal is to make a cheap tool that allows me to fake sensor inputs for automotive diagnostics. I'm thinking that I can do this with one variable resistor or potentiometer, but I need an electronics hobbyist to tell me exactly what I need. Thanks!
