Simple controller using Arduino Nano isn't recognized by Openflexure

If you install the Sangaboard library for python (wither on the pi, or another computer with python), by running:

pip install sangaboard

You should be able to check that this minimal example moves a motor:

from sangaboard import Sangaboard
with Sangaboard() as sb:
    sb.move_rel([1000,0,0])
    print(sb.position)
    sb.move_rel([-1000,0,0])

We are having some issues with the Nano motor boards. @jc2450 is building one this week to do some debugging.
