2015-04-09 (Th) Self Contained Haptic Distance Sensor

The small and elegant program written yesterday didn't use floating limits because after using the device for a few minutes it became apparent it was unnecessary. Currently the servo rotates to 0º when the distance sensor reads 2cm, all the way up to 180º when the distance sensor reads 450cm. If floating limits were used the minimum and maximum distances (2cm to 450cm) would have been determined by the minimum and maximum distances seen by the sensor since its last restart. Since the range of the distance sensor was a small window this method was unnecessary. If a future model used a distance sensor with a longer range it could become important. With this realization the only steps left were a finished rotating photo and instructions. The photos were taken but animated the next day.
