41 place the arduino's top edge along the underside of the
42 deck's holes closest to the edge of the deck.
43 on the arduino, there's a hole on the top left.
44 that hole should be mid-way between two of the holes in the
45 grid of holes on the deck.

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

62 are those fatter, thinner, or the same thickness as the
63 #6-32x3/8\" screws?]))])
64 (p [the "32" part is a measurement of how close the threads are to
66 this is related to the angle of the thread, which is also
68 it is a count of how many times the thread wraps around one

85 about to stick out on the top side of the deck.])

87 hole so the screw can come up through it.

92 (p [the arduino should still be flat against the deck still, just
93 as it was before tightening the screw.]))
96 (p [does the arduino stay with the deck when the deck moves?
97 can the arduino board still rotate a few degrees?
98 warning, if you rotate the arduino board too much, you
99 will unscrew it from the deck and you'll have to screw it
101 rotating a few degrees should be ok.]))
