How to use I2C in Arduino: Communication between two Arduino Boards In our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has only two wires while SPI uses four, and I2C can have Multiple masters and slaves, while SPI can have only one master and multiple slaves. So there are more than one… |
