As part of a project to communicate with a chip over SPI, I wanted to confirm that I could get two arduinos to talk to each other over SPI. The first arduino sends messages over SPI, and echos them back over the serial console for confirmation. The second receives messages over SPI, and reports whatever it receives over its own serial console.
