To Keep track of the current time you need a seperate module, because the arduino can’t do this for you. Therfore I found a DS3231 this is an “Extremely Accurate I²C-Integrated RTC/TCXO/Crystal”. This Real Time Clock (RTC) is the most precise you can get in a small, low power package. DS3231 Most RTC’s use an […]
