I have a few other related projects to work on. I'll take a break on the technical part of my worm project for now and think about the moisture sensing a little more. I need to finish my worm bin construction, put some worms in it, and install on outdoor wireless access point to connect to the the Raspberry Pi from the comfort of my house...
I had to edit a few of the step 1 and step 2 files to get the second sensor working with the others.
