these questions are about attaching the arduino to the deck. you used
a drill and drill bit to make holes for bolts to go through. we
drilled through the arduino into the deck.
- 0. [@0] what would happen if you used a larger drill bit than the one
+ 1. what would happen if you used a larger drill bit than the one
you used for drilling holes for the arduino?
- 1. why do people use drill bits that are smaller or the same size as
+ 2. why do people use drill bits that are smaller or the same size as
existing holes in circuit boards, like the blue arduino?
- 2. why did we use a drill bit that was wider than the body of the
+ 3. why did we use a drill bit that was wider than the body of the
bolt used to hold the arduino?
- 3. why did we drill through the arduino, rather than marking holes
+ 4. why did we drill through the arduino, rather than marking holes
and using the drill to make holes where the marks were?
+ 5. how does the drill hold onto the drill bit?
+ 6. what would happen if the drill bit teeth were not flat on the
+ drill bit?
+ 7. name some reasons for the arduinos placement on the deck.
+ 1. could it have been placed diagonally? why or why not?
+ 2. could it have been placed in any other location? why or why not?
+ 3. could it be upside-down? why or why not?
+ 8. should we drill at full speed? why or why not?
+ 9. how can you break the drill bit when drilling?
+ 10. the bolts used to attach the arduino are 6-32 bolts. the bolts
+ used to attach the motor to the motor mount are 4-40 bolts. Are
+ the 4-40 bolts fatter or thinner than the 6-32?
+ 11. if you see a bolt described as =4-40x1.25=" how long is it?
