26 (p [the "#6" part of "#6-32x3/8\"" is how big around the bolt is.
27 it is related to wire gauge.
28 bigger numbers mean larger screw.
29 smaller numbers means smaller screws.])
33 [in the motor assembly, there are #4-40x1.25\" screws.
34 are those fatter, thinner, or the same thickness as the
35 #6-32x3/8\" screws?]))])
36 (p [the "32" part is a measurement of how close the threads are to
38 this is related to the angle of the thread, which is also
40 it is a count of how many times the thread wraps around one
41 inch of the screw body.])

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

49 how many times will the thread wrap around two
50 inches of the screw body?]))]))
52 :title [fasten the arduino board to the deck]
53 (p [push the 6-32 screw into the deck from the underside and at the
54 same time, spin the 6-32 screw clockwise while looking
56 twist until the bottom of the screw is
57 about to stick out on the top side of the deck.])
58 (p [hold the arduino board flat to the deck and line up the arduino
59 hole so the screw can come up through it.
60 continue tightening the screw into the deck, spinning the same
62 tighten until the screw head touches the deck.
63 do not continue tightening after that.])
64 (p [the arduino should still be flat against the deck still, just
65 as it was before tightening the screw.]))
68 (p [does the arduino stay with the deck when the deck moves?
69 can the arduino board still rotate a few degrees?
70 warning, if you rotate the arduino board too much, you
71 will unscrew it from the deck and you'll have to screw it
73 rotating a few degrees should be ok.]))
