Digital output interface (0 and 1)

Being a beginner... I'm curious about the Digital output interface (0 and 1) mentioned in this article...

I can get the Analog value to work... but not the Digital Output value... From what I've read Digital input 0 & 1 (rx & tx if I'm not mistaken) need to be connected somehow... I'm not quite sure how, any assistance/information would be greatly appreciated.

Hi, I dont think that when it says "0 and 1" it is referring to Arduino outputs 0 and 1. It just means the reading is a 0 or 1 value, i.e. it is digital. Connect it to any Arduino digital input and the reading will be 1 if the moisture level is below the level adjusted by the trim pot, otherwise 0.

You are absolutely correct... I attached to digital pin 31 and and the reading was displayed. I was thrown for bit by the Analog println loop where as the digital println did not seem to loop...

No idea what you mean, but as long as you're happy!

Yep, gets me every time that one.
