Hi Ksj, This is what I have so far
View attachment 403881. I want to use the relay board to switch AC lights, fans blowers. Have you ever experimented with DC blowers or pumps? I'm wondering if going all 5V-12V DC might be wise. I was thinking about plugging the board into my lap top and poking around the Arduino software today. We'll see. Yes I am getting ready to harvest. Waiting for more amber trics to appear. I broke a small branch, dried it and sampled the Sour Crack. It's better than the last try. How's your new plant? I'm coming over to see.
