2 | ** mechanical questions |
3 | *** arduino to deck |
4 | these questions are about attaching the arduino to the deck. you used |
5 | a drill and drill bit to make holes for bolts to go through. we |
6 | drilled through the arduino into the deck. |

7 | 1. what would happen if you used a larger drill bit than the one |
25c1b477 |
8 | you used for drilling holes for the arduino? |
fb33ef7f |
9 | 2. why do people use drill bits that are smaller or the same size as |
25c1b477 |
10 | existing holes in circuit boards, like the blue arduino? |

11 | 3. why did we use a drill bit that was wider than the body of the |
25c1b477 |
12 | bolt used to hold the arduino? |

13 | 4. why did we drill through the arduino, rather than marking holes |
25c1b477 |
14 | and using the drill to make holes where the marks were? |

15 | 5. how does the drill hold onto the drill bit? |
16 | 6. what would happen if the drill bit teeth were not flat on the |
4b16c98d |
17 | drill bit? |

18 | 7. name some reasons for the arduinos placement on the deck. |
19 | 1. could it have been placed diagonally? why or why not? |
20 | 2. could it have been placed in any other location? why or why not? |
21 | 3. could it be upside-down? why or why not? |

22 | 8. should we drill at full speed? why or why not? |
23 | 9. how can you break the drill bit when drilling? |
24 | 10. the bolts used to attach the arduino are 6-32 bolts. the bolts |
25 | used to attach the motor to the motor mount are 4-40 bolts. Are |
26 | the 4-40 bolts fatter or thinner than the 6-32? |
27 | 11. if you see a bolt described as =4-40x1.25=" how long is it? |
