Acceleration values in the three axis change as you move accelerometer. When the accelerometer is level or at rest, the x axis acceleration is 0, the y axis acceleration is 0, and the z axis acceleration is 1. We can use the acceleration values to calculate the angle the accelerometer is at compared to the rest position. <\/pee>[\/et_pb_code][et_pb_gallery _builder_version=”4.6.6″ gallery_ids=”3986,3987″

  1. Create a level using your accelerometer and tilt angles. If the Roll and Pitch are between -2 and 2 degrees, print \u201cObject level\u201d. Otherwise print the angles to the user.<\/li>\n
    <\/p>\n
  2. If you are able to create a graphical program (for example, using Processing, Pygame, etc.), try creating a visual aspect to the level. Similar programs are available on the iPhone (shown below).<\/li>\n
