    I would like to sense current in 230V ,500mA circuit.
    How can i do that,is it possible to amplify the signal before giving to the controller or ADC

    You don't say whether you are measuring AC or DC, but I guess from the 230V that it is AC, in which case you need a current transformer. You can buy these but they are not ridiculously cheap. A google will lead you to lots of DIY versions. A totally outrageous version is here:

    thank you for the update.
    exactly am trying to measure from AC. I would like to make a set up in my circuit itself.
