Communicating between 2 NXT using RS485
We are looking for help understanding how to send information back and forth between NXT's when connecting them through port 4. We have a robot built with 2 NXT bricks to use more sensors and motors.
For example, the first task is to use an input from the sound sensor (plugged into the slave) to initiate the movement of a motor plugged into the master.
If someone could help us with getting started on this that would be great.
