Arduino based tank controller

[BlueAbyss]

Hmm, interesting... I'm doing something similar, but much simpler ie: no internet, just a standalone controller to keep everything in line (and run my LED lights) on my yet to be built 6 gallon. I just don't want to have to worry about such a small volume of water.

I'll be tracking this... and it's good to know that there is someone to ask questions of in this regard
