To keep things simple, we'll measure the acceleration only in the X axis while
the board remains horizontal. That way we won't have to deal with subtracting
1 g we observed before which would be hard because that
1 g could have X Y Z components depending on how the board is oriented.
Here's what the punch-o-meter must do:
- By default, the app is not "observing" the acceleration of the board.
- When a significant X acceleration is detected (i.e. the acceleration goes above some threshold), the app should start a new measurement.
- During that measurement interval, the app should keep track of the maximum acceleration observed
- After the measurement interval ends, the app must report the maximum
acceleration observed. You can report the value using the
Give it a try and let me know how hard you can punch
