#making an automatic watering system w arduino
#have it flashed to trigger the relays already for a variable amt of time
#which at the end of the day is basically all it takes + scheduling
#but now ofc its growing its own potential spinoffs...
#i wanna add a BLE module to be able to control the scheduling from like a phone
#which will then also require some minimal data storage...
#then the big question is rly how to power it...
#its probably gonna b within an extension cord length from the back door but dont wanna deal w unplugging it for rain etc
#so maybe like a weatherproof case w solar & a battery? but then ive gotta figure out the best way of battery-izing it....
#lithium seems like an overkill unless its like maybe lifepo
#& generally prefer lifepo over cobalt etc for safety
#but then ive gotta figure out how to add a charging circuit to it....
#anyway then once i have the app controlling scheduling i can also start integrating it into my home organizing/etc app?
#& ideally be able to like have a couple nodes like that?
#ah fuck also gotta figure out a case
#maybe just start w a nice n dirty project box til i eventually make a custom enclosure/PCB backplate for the assemblage
#maybe just put it next to our sprinkler box & just make the tubes longer so i dont have to fuck around w batteries for this?
#starting to convince myself of that idea tbh
#rn the relayboard has 4 guys...might b better to just have this as the master instead of having nodes so just get more relays
#centralize & dont have to deal w synching headaches
#maybe get like a multiplexer? not like this would necessarily need multiple at a time 1 at a time wouldnt b the end of the world
#& i have some cheap moisture sensors but dont rly trust em tbh
#esp w plants i intend to eat
#eventually tho maybe link some sensors into the system
#tho weather alone is probably enough to figure out
#oh! huh how would i do that....
#dont wanna have a whole ass wifi connection on the arduino
#or like parsing web results on there...
#& i dont rly wanna only know when connecting to my phone...
#so that seems to point towards some client that checks the weather prediction like once a day & sends that/consequences to arduino?
