How does a stop watch work?
The stopwatch works by pressing the start button when the event begins. For example, if you were timing a race, you would press the start button when the race starts. When the race is over, press the stop button. The time of the race displays on the stopwatch just as the time of day would display on your wristwatch.

What is digital stop watch?
A digital stopwatch can be a circuit displaying the actual time in minutes, hours and seconds or a circuit displaying the number of clock pulses. This is a simple circuit consisting of a 555 timer to produce the clock pulses and two counter ICs to carry out the counting operation.
