If you would like to connect a bluetooth module to the arduino of your LittleArm here is the wiring diagram.

Note 1 : A larger power supply (6V 2-3 amp) is reccomended to reliably power the arm at start-up and at high speeds. The original LittleArm power supply provides only 1 amp.

Note 2: While many tutorials (including this one) show how to connect a bluetooth to the Arduino without any extra components there is a danger that the module can be damaged. A safer way to connect the Blutooth module to the arduino is shown below.
