   1 * challenge-bot questions
   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
   8        you used for drilling holes for the arduino?
   9     2. why do people use drill bits that are smaller or the same size as
  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
  12        bolt used to hold the arduino?
  13     4. why did we drill through the arduino, rather than marking holes
  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
  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?
