I am starting a personal project of home automation and I have a raspberry pi and an arduino Uno board.
I want communicate raspberry pi and my arduino where my raspberry should be able to write and read signals to and from arduino.
The distance between them I think its going to be something around 10 to 15 meters.
What do I need for it? what kind of wires or other components I'll need to achieve my goal? I repeat: I do not want to communicate raspberry pi and arduino wirelessly.
