Help needed in merging codes; not sure what i need to get

Hello!

I'm trying to merge my code and have tried reading several tutorials on how to do it but I have no idea on how to get started on this piece of code.
Can someone help me please?

What I have :

  • humidity and temperature sensor (DHT11)
  • soil moisture sensor
  • water level sensor
  • a motor

The idea is to make a self-sustainable plantbox (a greenhouse) . If the humidity or temperature gets too high, then it will make the motor turn a little bit ( the motor is glued to a stick; turning the motor on will make the stick go higher which makes the roof of the greenhouse open; which helps with ventilation. This way it won't be too warm and the humidity will be fine too. As for the water level; the idea is that if the water level is too low that the plant will be watered. This was supposed to be automatic too but we don't have to do that. All that needs to happen is a LED lamp which turns on whenever the water level or soil moisture is too low.
Here are the codes, I'd be happy enough to just get a merged code; the rest will be do-able after.
(I dont have much at all, since I dont know where to start)

Thank you!

Sorry if I don't respond on time, I'm currently typing this on a school computer so I'll probably be able to only check the thread again by tomorrow or the day after.

It is easy to ,merge codes, but it may take additional coding to make them work together.

If you have no idea yet where to start I conclude that your knowledge about the fundamental structure of every sketch is low.

Take a look into this tutorial:

Arduino Programming Course

It is easy to understand and has a good mixture between explaining important concepts and example-codes to get you going. So give it a try and report your opinion about this tutorial.

If you have a smartphone or any other access to the internet.
You can learn something even in the afternoon.

best regards Stefan

And if @StefanL38 's link just looks like a giant wall of "what do I do now", and you are thinking "it can't be this hard" heeeeeelp meeeeee!".

Then you might prefer to go to youtube.com, search there for "arduino programming" or "arduino basics" or use your imagination to

find a video course that you think you can tolerate, sit back and dig in.

There are dozens, just look for the prettiest girl or some nice old man or that foreign guy who yucks it up quite a bit but he gets the job done, whatever.

Poke around until some tutor matches your level of experience and feels like you are going to allow them to learn you up, you will still have to put in the work.

Do it gradually. Try and combine two of them and get it working. Soil moisture and water level looks like an easy place to start as they're short.

(I had to change the DHT code a bit to match the librarty I have installed)

{
  setupMoisture();
  setupMotor();
  setupWaterLevel();
  setupTempAndHumidity();
}

  loopTempAndHumidity();
}
