#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?
