Hi all, I have been reading up on connecting 2 ardionos via wire library and this works brilliantly, but is there a way to connect 2 arduinos so that a serial command goes to both arduinos without having to use a sketch/code to control this, i.e. so I can send a serial command via one com port to b…

Sharing a serial connection between 2 ardiunos?
