Bluetooth wireless communication is becoming more and more common recently. In response to this trend, Cytron Technologies has came up with a new Bluetooth module called BlueBee, which provides hobbyists a wireless remote control on their microcontroller circuits thus robots through serial port communication service attached with BlueBee. In the section, a simple project will be constructed to illustrate how to use BlueBee for wireless communication to interface another Cytron product, breadboard friendly Arduino, BBFuino to control LEDs.
Nowadays, there have a lot of Android apps that can be used as a bluetooth controller to your microcontroller project. For example you can used Arduino BT Joystick to control your mobile robot, or IORelay Bluetooth Relay to control relays
