A bit of an aspirational project would be to control my kitchen sink with an Arduino. Why? Well mostly it would just be nice to be able to turn it on and off with a button. An appliance I put in my cramped kitchen makes it a bit awkward to get to.

Ideally I would be able to do fully hot or fully cold and fully on or fully off. It would be cool to be able to play with the flow rate or select a temperature in-between but feels like that would need much more fancy hardware. I would be satisfied with just the basics.

Other than just moving the knob to a simple switch better location there are some other things that could be nice:

1. Use my understanding of the flow rate to be able to turn the sink on for exactly 8 cups of water etc.
2. Turn the sink on automatically when another one of my IOT devices triggers it.
3. Probably other things(?)

I just cant figure out what kind of hardware I might want to drive using the Arduino.... Should I be looking for an entire sink I can control with the Arduino? An electronic controllable water valve for the sink? An electronic controllable handle... no idea. What kind of hardware can I look into for being able to control the sink with electronics?

I did some googling and could not find a lot of things that seemed useful. Most of what I could find was for small sinks that aren't actually your kitchen sink.
