Fridge water hookup

As a result, he drinks an awful lot of water. Refilling his bowl manually is a time-consuming task and sometimes I forget. I guess circulating the same water again and again with the dog spit and drool makes for a healthy breeding ground for bacteria. Anyway, I decided it was time to build an automatic water dish that refills itself. I bought an icemaker water hookup designed to attach the icemaker in a fridge to the water supply and my friend Frysteev helped me plumb it in.

This valve then runs to some clear tubing, down from the cabinets and into the water dish. Also in the water dish are two sensor wires, one at the bottom and one at the top of the dish. One is near the bottom and one is near the top.

The theory of operation is that the system waits for the dish to empty. It then makes sure that it really is empty. Then, it wait a certain amount of time say, 30 minutes to an hour for the water in the dish to evaporate.

Next, it turns on the water supply and waits for the upper sensor to register water. When it does, the water flow is turned off. Everything is run by an arduino hidden inside a cupboard. Thanks to my friend Andrew Kilpatric for helping me figure out the best way to sense the presence of water.

As it stands, to prevent corrosion and electrolysis, the water is only sensed once every 10 seconds and for only less than one millesecond. This should minimize the buildup of copper around the terminals.

There are numerous fail-safe features to prevent water overflow: This protects if the dog knocks the dish over or something.

View the Arduino source code for the dish here. The diode on the relay may be facing the incorrect direction -- it is there to pick up the bounce-back when the relay switches off and prevent it from reaching the Arduino.

The transistor is a PNA and simply provides the power to switch the relay.
