28 | :title [choosing drill bit] |
29 | (p [choosing the right drill bit depends on what job you are doing. |
30 | right now, we are making holes for screws to hold the |
31 | arduino to the deck. |
32 | this means the hole needs to be big enough for the |
33 | screw body to fit through. |
34 | we want the screw to stay put once it's in place. |
8923a50f |
35 | we also want the drill bit to be smaller than the |
36 | diameter of the thread. |
37 | the screw was chosen so that the hole on the arduino |
38 | was bigger than the body and smaller than the thread. |
39 | we will choose the biggest drill bit that fits through |
40 | the hole on the arduino.]) |
