I am trying to build Project which communicate multiple Arduino Nanos. I wanted to understand if Arudino Nano is capable of doing that, while doing research I came across post where it says communication with nano can be done up to 2-3 meter, where as my goal is up to 30 meter.
Project - I am trying intercom system, I have 4 Ring button at main gate, when user press any one of those 4 the Arduino will understand it and send to one of the 4 Arduino sitting at other place. Each Arduino will read that message if its for them they will perform activity if not they will skip it.
My problem is I am in selection mode and want know if Arduino Nano can handle that, communication is not that complex. It will be just sending 2/3 value max during communication. As I saw post of distance limitation, I just want get inputs from community. If you have any similar examples of serial communication between multiple Arduino Nano please let me know, I found several but it might save my time if I find something more similar.
