So I'm looking to use a few (2 for now, more later) Arduinos in combo with a single Raspberry Pi master. This is basically the setup I want:
What sort of protocol would be best for this type of thing? I'm looking at 1-wire for simplicity but after several hours of Googling I seem to know less about how to do it than before. The cause of this is likely that I couldn't find a lot of info for this.
If I do go with 1-wire, what will I need? Will I need shields for the arduinos? Will I need special sensors? Or is this simply not possible?
EDIT: Huh. I found a tutorial, I'll see if it works. http://blog.retep.org/2014/02/15/connecting-an-arduino-to-a-raspberry-pi-using-i2c/
