For proposal writing, after that we can make a research, identify and purchase the necessary components, now we make a proposal. In our proposal there is some info as follows:
1. Introduction
Special watches with
buttons that start, stop, and then zero the hands, used to time races. A stopwatch is a handheld timepiece designed
to measure the amount of time elapsed from a particular time when activated to
when the piece is deactivated. A large digital version of a stopwatch designed
for viewing at a distance, as in a sports stadium, is called a stop clock.
Real-time functions
traditionally controlled by two buttons on the case. Pressing the button on the
timer starts to run errands, and press the button a second time to stop it,
leave the elapsed time is displayed. A second later press the button to reset
the stopwatch to zero. The second button is also used to record split times or
lap times. When the split time button is pressed while the watch is running,
the display freezes, allowing time to pass when it is read, but the watch
mechanism continues running to record total elapsed time. Pressing the split
button a second time allows the watch to resume display of total time.
