Measuring three axis acceleration with an analog accelerometer

The upm library includes support for the three axis analog accelerometer breakout board in the pyupm_adxl335 module. The ADXL335 class declared in this module represents a three axis analog accelerometer connected to our board. The class makes it easy to calibrate the accelerometer and convert the raw values read from the analog inputs into values expressed in the g unit.

We will create a new Accelerometer class to represent the accelerometer and make it easier for us to retrieve the acceleration values without worrying about type conversion that are necessary when working with an instance of the ADXL335 class. We will use the ADXL335 class to interact with the accelerometer. The following ...
