31 (p [the "#6" part of "#6-32x3/8\"" is how big around the bolt is.
32 it is related to wire gauge.
33 bigger numbers mean larger screw.
34 smaller numbers means smaller screws.])

39 are those fatter, thinner, or the same thickness as the
40 #6-32x3/8\" screws?]))])
41 (p [the "32" part is a measurement of how close the threads are to
43 this is related to the angle of the thread, which is also
45 it is a count of how many times the thread wraps around one
46 inch of the screw body.])

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

59 same time, spin the 6-32 screw clockwise while looking
61 twist until the bottom of the screw is
62 about to stick out on the top side of the deck.])
63 (p [hold the arduino board flat to the deck and line up the arduino
64 hole so the screw can come up through it.
65 continue tightening the screw into the deck, spinning the same
67 tighten until the screw head touches the deck.
68 do not continue tightening after that.])
69 (p [the arduino should still be flat against the deck still, just
70 as it was before tightening the screw.]))
73 (p [does the arduino stay with the deck when the deck moves?
74 can the arduino board still rotate a few degrees?
75 warning, if you rotate the arduino board too much, you
76 will unscrew it from the deck and you'll have to screw it
78 rotating a few degrees should be ok.]))
