Is it possible to have a bidirectional Arduino connection with one wire; in a single-master multi-slave configuration ? Assuming all of them share the same 5V and ground lines.

Is it possible to have a bidirectional arduino connection with one wire?

As well as the 1 wire bus you can also have half duplex connections like the RS485

Only with out the differential drive but using tri-state outputs and a protocol to effect direction switching.
