    I have to build a circuit to collect the temperature data into computer and temperature ranging from 0C to 125C
    The components i'm using now are LM35 as temperature sensor with 10mV/C and PIC18F4520.
    Im totally new in electronics so i need advise and guidance.
    As far as i know, the Vout from LM35 is too small to read by PIC so i have to amplify the Vout, but i dont know how to gain it, any comment would be appreciated. :)

    thanks
