New to electronics-question

  1. Oct 4, 2010 #1
    Hello
    I'm new to electronics and trying to learn. I thought the best way for me is to watch videos on youtube and ask questions from some more knowledgeable people than me on the subject.

    That being said, I want to try what I believe to be a simple project.
    I want to measure the fluid level of a plastic cup with out having any sensors inside the liquid.
    Help me out if if you see were I might be falling off the wagon per say.

    1 - small 2 x 4 in board
    1 - LM339N IC Quad Diff comparator 14 dip
    4 - led
    1 - push button NO
    1 - Potentiometer (size unknown)
    several resisters (size unknown)
    2 -copper contact pads

    any help in this would be greatly appriciated.
    What im trying to make this for is to measure the fuel in my ultralight gas tank.
    which is out of sight while flying.
    Thanks in advance

    Sounds like a homework problem - what have you tried / thought about so far.

    first I thought I would get a breadboard,and the components listed above and do some testing. just wanting to see if im on the right track,or if their maybe a component that would be needed or some other knowledge im not thinking of

    You want to do what ?
    Measure fluid in a cup or the gas level in a tank ?

    All your trouble is the sensor. Do you know what sensor you will use yet ?
    Once you have a reliable (mechanically and electrically) sensor, the rest is easy.
