Rubik's cube Robot solver

First cube moves according to Singmaster notation (see post #8)
< D, B, B', D' >
This sequence will finally bring back the cube to its initial position


>> Video <<

Those 4 moves are hard coded in the Arduino sketch

I will now prepare a sketch with all possible moves:
F (Front), B (Back), U (Up), D (Down), L (Left), R (Right), plus the " ' " and " 2 " variants

For debugging purpose, moves will be entered through Arduino's serial monitor

EDIT: see post #242 (code)
