NEWBIE HERE!: Can a "Uno" talk to two other "Uno"s at the same time via bluetooth or wifi?

I know it can talk to ONE other Uno (via "Xbee" I think) but can it talk to TWO other units?

I have just started today to learn and was thinking about this question... at this moment it is just a "can it do it or not" question. Thank you.

Yes, if the communication method supports it.

You would not want to use Serial to do this, but many wired and pretty much all wireless communication protocols support multiple nodes on the same bus. The choice of which to use can be a difficult one though.

Thank you :slight_smile:
