dear friends.
i have doubt. have made gardening system turns on , off solenoid valve @ particular time. , complete timing taken care of millis() function.
the program working fine have doubt if millis work fine atleast month or so? in case having experience using millis() long durations, kindly share experience.
timing accuracy not issue me, know if can manage timing reliably millis() or should go external rtc.
