    Can anyone tell me the difference between the way VR1 is wired as opposed to VR2? VR1 looks like a variable resistor, but what is two called? and how would I connect it?
    Thanks in advance.

    Can't read your picture but a two terminal variable resistor is called a rheostat and a three terminal variable resistor is called a potentiometer.
