I have a project that I plan to use the Arduino only a few minutes each day. I am planning on waking it up with a DS3231 board. I have looked at several tutorials to set the RTC's time. Each one has the time hard coded into a program. This cannot be that accurate. How to I access time from my computer or the internet and use that. In my case it does not really matter that much. I want it to run sometime late evening or early morning. The exact time does not matter but I would like it to be consistent and as long as I am setting the time, I might as well get it right. Any advice would be appreciated. If there are other ways to wake the arduino up every 24 hours, I would consider those also.
