Hi guys,

I were trying to connect two arduinos by I2C , in particular an Arduino Yun with a Arduino Mega, i follow the 2 codes of the wire libray , the master and slave one, it works if I connect both arduinos to the same pc but if I connect the arduinos in different pcs it doesn't work....
HELPPPPPPPPPPP :confused: :confused: :confused: :confused: :confused:

Connect the grounds of the two arduinos. When they are both on the same pc, the grounds are connected through the usb.
