Funny you said that as I started another thread asking for a way to remove the analog pot from my analog controller and someone replied with the same exact idea of using a servo. Right now, my garden has so many wires and timers and plugs and cords everywhere it is such an eye sore. I'd like to have everything with a cord just ran into something very clean and have the Arduino control all of it, but more important to me is the ability to access my garden wirelessly and have the ability to control or change any part of it from my smartphone. When I get to where I'm going with this, I will share it on youTube with code, pinout schematics, the whole 9. The tough part is getting to that point, but I don't have to tell you that, hehe.
