Interfacing arduino uno and bluetooth dongle.

Hi, Is it possible to interface bluetooth dongle with arduino uno?? If no, can you suggest any other bluetooth receiver(cheap one) for uno?

Thanks in advance.

If you are referring to a USB device, it is remotely possible. The dongle is almost certainly a USB slave, as is the Arduino. Two slaves can not talk to each other. There must be a USB Master (host) involved. Fortunately, there is a USB Host shield available for the Arduino. Unfortunately, writing a device driver is not a trivial operation. The limited memory and code space on the Arduino makes it even more of a challenge.
