Rain Barrel control

I think I now have a working control for the rain barrel, with a moisture probe. This will prevent watering if the ground is already wet. I have a new PC board made and tested and just waiting for the weather to break a bit to get the barrel hooked up to test it. If all goes well I will add the design info to the rain barrel page soon. The whole control is pretty basic with only one adjustment for the probe so it should be cheap and reliable. Just don’t expect any bells and whistles.
