Hi all, I'm currently trying to set-up a hydroponic system. However I have run into some trouble. I'm trying to figure out a way to take the last result from the conductivity meter in Vernier Logger Pro software to paste inside a area inside Arduino code. The aim of this is to act as a trigger value to turn a relay on/off to pump nutrients into my system. I'm also trying to figure out how to define this range parameter to allow the relay to turn on/off. I'm a complete noob when it comes to this stuff. I know the parts I need but not how to program it to do the things I need.
Any and all help would be greatly appreciated.
