Mountings:

This is an important factor that needs to be considered while building this prototype. If the gesture controller is not mounted properly, then desired readings are not obtained from the device leading to improper results.

Baud Rate:

Note the baud rate of different arduino changes according to the processor or controller present within the development board. Hence it is necessary to make a detailed study regarding the baud rate of the board being used. These values needs to be used in the Java program.
