Hello
Im in the start of a new project where i nead to connect at least 25 Arduinos in a network. I have first tried I2C but i going to be at the maximum 10 meters betwen them wher I2C have problems over 1 meter. What bus should i use? I prefer to use somthing thas bult in to the Arduinos and not any extra bords. 2 way communication is necessary. It would be nice if i can talk from the master to a slave and slave to slave. But i can be done whid Master to slave and slave to master.
