Arduino Daily Schedule Timer On-Off Using RTC Module with Memory Backup If Power Cuts

Hello friend, today I am going to show you how to make a schedule timer circuit using Arduino with RTC module. I already made this project a long time ago, but this version is more stable and accurate. In the previous version, all the settings would have been reset after the power cut-off, but this problem is solved in this version, in the previous version time can be set to a maximum of 8 hours, but in this version, time can be set up to 23.59 hours. So let’s start …
