28 | (p [choosing the right drill bit depends on what job you are doing. |
29 | right now, we are making holes for screws to hold the |
30 | arduino to the deck. |
31 | this means the hole needs to be big enough for the |
32 | screw body to fit through. |
33 | we want the screw to stay put once it's in place. |
34 | the threads of the screw will grip the edges of the |
35 | hole it's going through.]) |

76 | (p [the "32" part is a measurement of how close the threads are to |
77 | each other. |
78 | this is related to the angle of the thread, which is also |
79 | called pitch. |
80 | it is a count of how many times the thread wraps around one |
