Take a look at the above
tutorials before continuing
to read this tutorial.
           One of the newer sensors to come about in recent times is the accelerometer. Granted the idea and implementation of a sensor that measures acceleration has been around for a long time the newer technologies available to industry have made them super accurate.
           The MEMS Accelerometer usually comes in the smallest surface mount package and can detect acceleration in up to 3 axis. This tutorial will cover capturing data for onle one axis. The PIC will be used to capture the data and make sense of it.

ADXL320 Accelerometer

The PIC 18F452

Purpose & Overview of this project
           This tutorial is meant to show you how to use a PIC microcontroller to take data from a MEMS ADXL320 and make sense of it. To demonstrate that it works the 'tilt' sensing attribute of the accelerometer will be used.
           A simple blinking LED will be used to gauge the acceleration being applied to the sensor.
