3D print adapter object. STL file located at http://www.thingiverse.com/thing:588294
Attach a BYJ48 stepper motor to the adapter. More information about the stepper motor used at http://www.instructables.com/id/BYJ48-Stepper-Motor/
Carefully solder header pins to the additional I/Os available pins in the Ardunio bit. for easily connecting the stepper motor. Visit following link for valuable information about referred pins. http://discuss.littlebits.cc/t/using-the-additional-i-os-on-the-arduino-bit/1019
If needed assemble the Lego Leaning Tower of Pisa -http://architecture.lego.com/en-us/products/landmark/leaning-tower-of-pisa-21015- The tower will be raised by a partial stepper motor rotation.
