the deck.

with the first screw, the arduino can rotate around one
- point on the deck.])))

+ (p [the second screw limits rotation a lot.
+ it also makes translation even more difficult.
+ it might even be too small to be detectable by directly
+ looking at it.])
+ (p [to choose where the second hole and screw should go, we should
+ keep in mind that the goal is to attach the deck to the
+ arduino.
+ this means minimizing rotation and translation.
+ the picture below shows that the second hole should be as
+ far as possible from the first hole, since that minimizes
+ rotation.]

+ hold the arduino down as before, and drill through the hole
