I'm currently working on a Hydroponic system and trying to implement a timing schedule for both the grow lights (5V Relay) and the pump(5V Relay). I would like for Lights to come on at 06:00 and turn off at 19:00. The pump to turn on at 06:00 and turn off at 06:05 and turn on an hour later and run for 5 minutes. The pump will need to repeat this until The sketch which is based on the RTC 3231 below complies with my Arduino Uno fine, with no errors, using both versions of IDE 1.8 and 2.0. However, when I try to compile it for my Uno Rev2 Wifi (ATmega4809), I get a laundry list of errors(see below). I'm sure it has something to do with the different chips between the two models not matching with what is coded in some of the sub folders but I have no idea what I am doing and do not want to screw it up worse than what it is currently. I'm using the library from rinkydinkelectronics but I have tried several of the DS3231 Libraries from IDE. I have tried to google this issue and I guess I'm too stupid to figure it out with my extremely limited coding knowledge(if you can't tell from the code below). I tried some of the examples and had issues compiling them as well. If anyone has any ideas or a library that will work with the RTC and UNO R2 Wifi, it would be appreciated. If so, please reply in Laymens Terms lol... Thank you!
