Hi,

I'm new at this but i would like to develop a laptop battery charger "interface". Is it possible, via USB, to read my laptop's battery level and use it in the programming?

thank you.

Hello? Hello? Are you there?

That is the ONLY kind of information you can send from the Arduino to the PC. You have to have some application running on the PC that can send the battery voltage information back to the Arduino when it asks for it (or that pushes it to the Arduino whenever it wants to).
