I've been stuck on this project for about two weeks now. I wanted to make just moisture sensor and water pump and nothing else.
I've tried to follow this:
As for moisture sensor, I tried to use this design:
I have used so many codes that I lost count. I mostly just find code for everything then remove everything that isn't moisture sensor then upload it.
One of the problem I have is... It seems like no matter what I do, the sensor never seems to work or have any input. I would successfully upload it and everything only to have no reply from sensor. I couldn't measure anything.
Where am I suppose to see the amount of moisture in the soil and how do I get it to show? I really need help with this.
Thanks in advance.
