RTC time for Event Scheduler

Hi All,

I am new member here. I have a question regarding if it is possible to use the time from RTC to create a scheduler? For example, I want to trigger a relay every four hours, I am thinking if I can use the time as a trigger. Thanks in advance. More powers to all.

Yes you can, and the RTC library supports the alarm function. There are a lot of examples of this on the web.
