    Hi all. i am currently trying to build a energy monitor station with an arduino and labview. I am using a CT clamp sensor to measure roughly 1.3 amps. Because this is so small the sensor outputs an AC signal in Mv which the arduino cant read. So i built a non inverting Op amp circuit to amplify the signal of my current transducer. The signal is now approximately 2.40v AC. When i connect this to the input pin on my arduino i cannnot seem to get a reading at all. Any help greatly appreciated as i am out of ideas and not very familiar with with the whole operation

    Use ADC to take reading of ac voltage.

    Oops, you did say you use labview.

    Try using Arduino IDE Serial Monitor. It is pretty easy to use. See if that works.

    I have my adruino connected to my PC via usb so no problem there. I cannot seem to read the AC voltage coming in
