Hello, i'm new in the community, i search information about creating a kind of network with more arduino. I use "arduino Mega2560" for the master (or the server?) and arduino uno for the slaves.I think about ethernet, with ethernet shield, but it's expensive because i have to use one shield for each arduino and a ethernet switchI need a full duplex connection, for send information from the master to the slaves and receive status and other information.The rs495 is good, but isn't full duplex.Excuse for my english if there are some errors, but i'm italian.Bye, Marco

The rs495 is good, but isn't full duplex.
Can i use ethernet connection for more arduino, without any PC?
maybe i use rs485... connecting the control pin of the MAX485 to an output of arduino, i can control the direction of messages (TX or RX).. Is it right?Maybe is the better choice...Thanks, MarcoPs: now i do some experiments...
