    hi everyone ,
    in my projet i use the arduino for voltage aquisition from the solar cell toward the laptop.
    when :(i make a constant resistance, the arduino send a good measure,
    but my probleme is when i make a variabale resistance, in this moment the arduino sent a false measure?
    can anyone help me!

    Don't make variable resistance.

    Maybe you need to let the ADC to settle down then. Let it take several measurements in a row, then either use one of the measurements or calculate the average of the several measurements that you took.
