I have seen many of this similar questions about the RTC. I'm currently trying to setup my Arduino to trigger my relay to close on monday and wednesday at 5pm -5:10pm.
I know I have to use
now.dayOfTheWeek() will return you the weekday number
and now.hour() will return you the hour
set a pin
Anyone ever setup date and time with the RTC on the ardunio?
