+    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.
+**** drilling
+     1. what would happen if you used a larger drill bit than the one
        you used for drilling holes for the arduino?
-    2. why do people use drill bits that are smaller or the same size as
-       existing holes in circuit boards, like the blue arduino?
-    3. why did we use a drill bit that was wider than the body of the
-       bolt used to hold the arduino?
-    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?
-    12. on a =4-40= bolt, how many times does the thread wrap around
-        one inch of the body?  4 times?  40 times?

+        40 times?
         1. how many times does the thread of a =4-40= bolt wrap around
-           two inches of the body?  8 times? 40 times? 80 times?
-    13. what part of the screw does the screw driver go into?
+           two inches of the body?
+           8 times?
+           40 times?

+     4. what part of the screw does the screw driver go into?
+**** part placement
+     1. 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?
+     2. why are the motors between the wheels?
+     3. why are the motors pointed towards the caster in the back?
+     4. why are the battery packs between the wheels and caster
+        (roughly)?
+     5. where is the breadboard?
+     6. where is the caster?
+     7. why is the caster in the middle of the back, instead of on the
+        left or right?
+     8. should the black chip (motor controller) be on the left or the right
+     9. why should the chip be on the right?
