So now we have our Real Time Clock up and running and we can use in any Arduino Project. As a second example I connected an LCD to the Arduino and printed the time and the date on it. Here’s the source code of this example: /* * Arduino DS3231 Real Time Clock Module Tutorial *...

Achess clock, or similar countdown/countup timer clock. You may need to add an RTC clock chip to the board, but this is not particularly difficult. Optionally, you might want to add a second momentary contact switch, so that each player has one. Now this would be an interesting and ...
