Question

Batteries

Hello. inspired by the topics one , two , I decided to make myself a simple system for shutting off the water supply.
The idea is to buy components from aquastorage, namely the following electric faucets: And a set of wireless switches from NooLite:
I want to connect the faucets to hot / cold water input. Power them from batteries or a power supply (have not decided yet). And make the switch from the NooLite kit (so as not to stretch the wires to each electric crane). The result should be a simple solution, when you press one of the buttons on the NooLite panel, the water opens / closes, I think the switch itself should be hung somewhere near the front door.
But the problem is that I don’t know how to correctly implement it - I can assemble / twist the wires / connect the taps without any problems. But some questions arise. For example, how to make sure that by pressing a button once, the power is supplied to the tap just enough so that it has time to close / open (probably some kind of timer or feedback is needed)? Further, how to properly connect the control controller to the crane itself - is it possible to simply hang it as a load (controllers are designed to work with a load that consumes 220 volts, and cranes consume only 12)?
PS Perhaps I have not yet realized something myself, so I'm waiting for comments from you!

> Further, how to properly connect the control controller to the crane itself - is it possible to just hang it as a load?
The most that can happen is that it won't work. Although in general they are not very suitable for you, because. to open / close the tap, you most likely need to change the polarity of the current, which is not provided for in them.

Answer 2

No microcontrollers are needed here: an elementary single vibrator is assembled on purely analog parts. In order for each button press to invert the voltage, you will need a simple D-flip-flop.
But if you want to connect more pressure sensors, all sorts of screens and other tinsel, then yes - you will need some kind of microcontroller.
