Professional athletes, car drivers, bicycle riders need to keep practising by measuring their lap timings. While practising alone it is not possible for them to start and stop the stopwatch each time. At such time they need to focus on their performance instead of keeping track of the watch. So here we propose a system that can be work by user as a wrist watch. The system consists of a push button that needs to be pushed by user to start the system. On button press the microcontroller starts timer. The system also consists of an IR sensor pair, that is to be placed at finishing line. As soon as the user crosses the IR sensor pair it sends a signal to system to stop the timer. The time gets frozen in the system for user to check. The user may later reset the system using a push button provided on it.
