A digital stopwatch serves as a versatile timekeeping device with several practical functions. Let’s explore its features:

1. Elapsed Time Measurement:

   • A stopwatch is designed to measure the amount of time that passes between its activation and deactivation.
   • In manual timing, a person starts and stops the stopwatch by pressing a button.
   • In fully automatic mode, sensors trigger both starting and stopping.
   • The elapsed time is displayed prominently.

2. Precision and Accuracy:

   • Digital electronic stopwatches are more accurate than their mechanical counterparts.
   • They utilize a crystal oscillator timing element, ensuring precise time measurement.
   • Some digital stopwatches even include date and time-of-day functions due to an inbuilt microchip.

3. Additional Features:

   • Beyond basic timing, digital stopwatches may have added functionalities:
     • Countdown Timer: Set a specific time interval for countdown.
     • Multiple Time Recording: Record split times or lap times during an event.
     • External Sensors: Some models allow triggering by external events, enhancing accuracy.

4. Applications:

   • Sports Timing: Used in races, sprints, and other athletic competitions.
   • Scientific Experiments: Precise measurement of time intervals.
   • Industrial Timing: Monitoring processes and operations.
   • Everyday Timekeeping: Present as an additional function in wristwatches, cell phones, and computers.
