Communicating with Laptops or Tablets or Smart phones

Hi... I want to send some analog input from Laptop or tablets to the arduino Uno

Can Arduino Uno communicate with Laptops or Tablets through USB port?

This seems a strange question.

Have you got a Uno or have you looked up its details?

Does it have a USB connector?

...R

Yes, you can build applications using something like Visual Studio, and communicate with the USB port. Lots and lots of examples around the web.

Thank you sir.. Actually I'm totally new to this micro controller so I don't know many things.. Can you send me some links about this ?

Just google 'visual studio arduino' or something along those lines.
