/* MIZAH BIT SCRIPT v1
This is a working version of the mizah bit script in which a flex sensor
and thew x and y component of an accelerometer are feeding to the xively
datastream online. In the next version, LED triggering capabilities will
be built in and the accelerometer outputs will be calibrated to fit within
set ranges
