Voltmeter without external digital screen

I want to make a simple voltmeter to read voltage level from my computers screen. I want to measure the voltage level from my audio jack's output.

I don't have a digital screen. Is it possible to turn voltage values to PC?

Thanks,

I voted for the first one. hope that helps.

I voted for the second option.

Yes, it is possible.

How possible? Could you send me the code ?

Entirely possible. Take a look at the AnalogInOutSerial example sketch.

Is there an option for "buy a digital multimeter with a serial output"?

i think one needs to open monitor after running the circuit. and the voltage =5*"that number"/1024
