i want check mobile Battery % with Arduino Host USB how can it possible.?
Hello nahush
Welcome to the best Arduino forum ever 
Yes, it is.
Choose an Arduino board that supports a USB connection and then design and program a sketch for your project.
Mayby, it depends on your circuit and code. Are you trying to make a state of charge indicator? Is the battery directly connected to the USB? Post an annotated schematic showing how you expect to wire this.
USB is generally powered with 5V from a voltage regulator, You will not get any information from that 5V source.
Thanks. I am loooking for Bluetooth App & app thrue control mobile battery charge connect with PD
What is this Host USB of which you speak? Host implies that is trying to act as a USB host do you really mean that?
Do you mean Pure Data when you say PD. The graphic programming language for music and sound generation.
I can't see how that would possibly work.
PD mean power delivered. Host mean Ready mead arduino board came with usb
Maybe you mean Ready made, as mead is a drink containing fermented honey.
Well I don't understand that word either. So maybe I will give this post a miss.
Good luck with your project.
i have less know USB host Arduino mean
Help explain your meaning by making a well-labeled drawing with all the devices involved.
Probably best to type full details in your native language into Google Translate and then copy the result here.
