Digital Stop Watch Circuit Diagram. Circuit diagram of digital stop watch. Sir i tried this circuit of yours digital stop watch and it works fine thing is the hundredth of a second works but when it comes.
The 7 segments marked as s for seconds and m for displaying minutes in the above circuit diagram. The circuit may be easily fixed and built on a general purpose pcb. Digital stopwatch circuit diagram.
The above circuit consists of the ics which we discussed before.
The proposed digital stopwatch circuit will work off a 5v supply inputs. With the frequency of output signal given by f 1 44 ra rb c we can calculate the values of c. And a part for turning on and off the correct output pins to display the numbers from each of the variables in each of the displays. A timer part that updates 4 variables to contain the correct numbers for each of the four displays.
