This doesn't include a rtc, but an rtc is not as important in a stopwatch application anyway.http://fritzing.org/projects/arduino-lcd-stopwatc...It is a simple stopwatch, and if you want to incorporate an rtc simply connect it to I2C like I did and use the setRTCTime() and readRTCTime() methods to access the time from the rtc. From there, you should be able to use arithmetic to calculate the passing of time.Best of luck!
Hey, this project was designed to be a clock rather than a stopwatch. However, you could use a similar hardware design and make use of the RTC to keep good time and print the output to the LCD.Thanks!

The format for the parameters of setRTCTime() is (sec, min, hr, day of week, day of month, month, year)For example: setRTCTime(0, 3, 23, 4, 15, 7, 17);Hope this helps!

My mistake. Thanks for pointing that out! (:
Gotcha- my mistake. Great work and thanks for sharing this!
Nice. You'll need to change your code every year as day light savings times starts and ends on a different date every year, though. Also I would change your 'int DST' to a boolean since you are using it as 1 or 0, and a boolean will use less memory than an int.
Thanks! I have not written code to handle daylight savings time. You could write this code yourself based around existing lists of data, though it would most likely be easier just to manually adjust the time as needed.
