Electronic – Arduino and Bluetooth USB dongle


Is it possible to use a mini USB Bluetooth dongle like in the following picture in order to improve my Arduino Uno, so it can comunicate with other Bluetooth devices?

If it is, how can I do that?

Best Answer

It is, in theory, possible, to make your Arduino talk USB to the Bluetooth dongle. Usually, however, the better solution is to buy a serial-to-bluetooth module, and connect that to the serial pins on your Arduino, or to pins on Arduino compatible usable by the SoftwareSerial library.
