This exercise considers the methods available for dealing with time measurements in physical computing. Software or hardware can be used to directly measure time or time intervals. Time intervals can then be used to make frequency measurements by counting the number of events that occur in fixed units of time or determine speeds and accelerations when distances traveled in time intervals are evaluated.

Determinations of time of day and the time between events are important parameters for gathering scientific data ...
