The stopwatch we are going to design is in “MM:SS:mS” (Minutes:Seconds:Milliseconds) format, the maximum time duration it can measure is 99:59:99, next count will be reset “00:00:00”. The design of the proposed stopwatch circuit: These days a digital clock with stopwatch functionality can be found everywhere for dirt cheap price but, building a digital stopwatch our own is next level of fun and enthusiasm towards learning digital electronics. Stopwatch needs no introduction we use them at many points of our life to measure timings for several purposes like: During cooking to avoid the food to either overcooked or undercooked, during a sport event or even at science lab.

We can start and stop the count of the stopwatch at any instant and also can be reset to zero to measure the timing of a new event. Stopwatch is a timer which is used to measure an event anywhere from milliseconds to several hours.
