Homework Help: Potentiometers and sensing in a greenhouse window

  1. Feb 19, 2008 #1
    1. The problem statement, all variables and given/known data
    I am doing a piece of work on potentiometers/potential dividers and i need to design a sensor circuit to detect 60 degrees of movement of a greenhouse window. I then need to be able to see the position of this window on an analogue display (this is a 5V voltmeter with a pointer/dial). How do i create such a circuit?


    2. Relevant equations



    3. The attempt at a solution

    I know that i need a rotary potentiometer and a 5V voltmeter (with analogue display) but how do i connect this apparatus together in a circuit and what other electrical items do i need? Diagrams would be extremely helpful. Many Thanks
