In this tutorial we are going to see about Arduino master slave serial communication. Arduino I2c communication between Arduinos, it can be helpful to set up two (or more!) Arduino boards to share information with each other. Connect pin A5 (the clock, or SCL, pin) and pin A4 (the data, or SDA, pin) on the master Arduino to their counterparts on the slave board. Make sure that both boards share a common ground. In order to enable serial communication, the slave Arduino must be connected to your computer via USB.
