Arduino SPI Tutorial

Arduino SPI Tutorial

In this tutorial we learn about SPI protocol and how to use it in Arduino. We will use SPI Protocol for communication between two Arduinos. Here one Arduino will act as Master and another one will act as Slave, two LEDs and push buttons will be connected to both the arduinos. To demonstrate SPI communication, we will control master side LED by the push button at slave side and vice versa using the SPI Serial communication protocol.
