             wrench, can exert force to spin the screw.]))

     (p [push the 6-32 screw into the deck from the underside and at the
              same time, spin the 6-32 screw clockwise while looking
              down on its head.  twist until the bottom of the screw is
              about to stick out on the top side of the deck.])
     (p [hold the arduino board flat to the deck and line up the arduino
              hole so the screw can come up through it.  continue
              tightening the screw into the deck, spinning the same
              direction as before.  tighten until the screw head touches
              the deck.  do not continue tightening])

             as it was before tightening the screw.]))

     :title [assessment]
     (p [does the arduino stay with the deck when the deck moves?
              can the arduino board still rotate a few degrees?
              warning, if you rotate the arduino board too much, you
              will unscrew it from the deck and you'll have to screw it
              back in.  rotating a few degrees should be ok.]))
    (subsubsection
     :title [arduino board move relative to deck]
     (p [without any screws, the arduino board can move independently of
                 the deck.])
     (p [with the first screw, the arduino can rotate around one point
              on the deck.])))
