Real Time Clock Module Reset I just had a pretty simple question about the RTC Clock Modules, more specifically the DS3231 RTC. Once calibrated and running on my Arduino if I were to unplug it and plug it back in, will the time and everything reset and require another calibration, or will it work like a computer that, even when reset, retains the correct time and date. Thanks!
It depends if your module has a battery backup or not. A bare chip, by itself, will loose everything. That's why many breakout boards will have a small lithium cell on them to retain everything when the power is removed.
