I think it’s important that i start out explaining a little about my project, so i am currently designing a cheap, reliable hydroponics system, i’m planning on making it all open source when it’s done.
but i needed a micro-controller for the watering system, and possible future additions, i have a some basic understanding about how code works, but it’s very limited and basic, i had literally no idea what i was doing, but i wrote the code below took me 5 hours to look through the community for my desired functions and get something that worked so bear with me it’s a mess.
i tried commenting the functions that i understand, to help myself in the future and to show you guys what i understand of the code
as you see in the code i uncommented all the DHT sensor stuff, because that’s what’s been annoying me i got all the other code working, but now i can’t get the DHT sensor written in there, any feedback on my code, what am i doing wrong, is it formatting, or simply a question of how i’m placing my code, also i’m experiencing connection issues with the app?
appreciate all help <3
