Is it possible to link a dozen arduino and one raspberry pi?

Есть десяток arduino uno управляющие различными реле и слушающие датчики в loop. Сейчас появился raspberry pi 3 и хочу поставить её мастером над всеми arduino: поставить веб сервер и смотреть состояния реле и управлять этими реле если захочу. Что мне посоветуете в качестве управления и прослушки arduino. i2c, ethernet shield?
ЗЫ: Все ардуинки и малинку хочу запереть в одном шкафу и прокинуть новые провода от этого шкафа.

There are a lot of options, but if everything is nearby, I would choose a thread like a CAN bus. Can be connected directly via COM or RS485.

so many additional factors. if you already have wires and you are not embarrassed by the price of the shield - do it on Ethernet. everything is simple there. And the distances are good. No wires - I would consider a radio. the blessing of examples in bulk.

I would probably do everything through 1-wire, it’s convenient that there is a minimum of wire, plus there are already many ready-made examples on the Internet, and, of course, you suddenly have to transfer the controller - it will be very easy to do. Well, of course, a minimum of finance for reworking the system.
