BeanMove
iOS program to demonstrate how to use the LightBlue Bean's accelerometer to register movement.
The Bean should be oriented so that the battery is towards the back, and the long axis of the bean is up/down, with the holes at the bottom:

When you first run the program, click on the "i" at the bottom right corner, which will allow you to choose a Bean.
Once back in the main window, if you connected to a Bean, the x-axis acceleration will be listed in the text box, and will change due to the Bean's movement.
If the bean moves significantly left or right, an arrow should swish left or right, respectively.

Known bugs
-
Occasionally, the program will crash -- unsure why.
-
Because the program is basing its left/right announcement on a simple acceleration measurement, slowing the bean down in the opposite direction can also trigger it. E.g., if the bean is on a sliding door, it will report when the door opens in one direction, and then as it stops (as the acceleration is in the opposite direction, and significant).
