Application Idea
Using the tilt code from Experiment 1, you can create a 3D joystick by mounting the Memsic 2125 and a
pushbutton in a small, spherical enclosure (like a tennis ball). With just three pins you can measure tilt
of each axis and the status of the switch.
Parallax BOE-Bot.
Using TOut
Since the Memsic 2125 is a thermal device, the temperature is available from the TOut pin and can be
measured using an external analog to digital converter (i.e., LTC1298).
