Assignment . Total points: 5 Create a simple app to read accelerometer and gyroscope events Create a drop down list with two options - 'accelerometer' and 'gyroscope Create a table with 3 rows - one each for X, Y and Z axes. Populate the table with current X, Y and Z values based on the selected sensor from drop down. . . Assignment .
