Hey, I have been a given a project in university which is making a stopwatch, and the teacher told us to use the internet to find the solution for it is our first time doing this kind of projects. Anyway I found a site http://www.circuitstoday.com/digital-stop-watch showing the circuit diagram. So Can someone explain to me how exactly this circuit work giving details on how the whole system work, what are the purposes of the chips and the rest ?? Or if you know a website that explain everything about my project, can you give the link?? Thanks
And got the following answer:
The 555 provides a square wave timing signal, basically a series of regularly timed pulses. The other chip is a multifunction device which combines several tasks related to the counting of the pulses and the display of that count. Seven segment led's are used to display each digit. The four digits are multiplexed, each digit is switched on one at a time in a rapid sequence so fast that your eye is fooled into seeing multiple digits lit up and displaying digits. Multiplexing allows the sharing of seven output pins used to drive individual led's across several digits. 7 segments plus 4digits thus require only 11 pins instead of 28 pins. Switch S1 changes resistor value so that the 555 timer produces Pulses either one second or one tenth of a second apart. VR1 is an adjustable resistor that allows the unit to be calibrated. Switch S2 activated the counter which then starts counting the pulses from the 555 timer Switch S3 resets the display to zero. Although this is a functional circuit, it is more useful as an educational activity than a practicle timer. The reason is that its accuracy is limited by the limitations of the 555 timer chip on which its based. If you were to build this circuit it would work well enough but don't expect olympic swiss timing results.
