In Part 1 we created the Arduino sketch and Python script to handle shutting down the Rpi gracefully. In Part 2 we will be prototyping the the circuits to make sure they work as expected.

FamiPi Power Switch and shutdown handling: Part 1
Below is the start to my arduino nano based power circuit for Famicom based retro pie build. The goal of this Arduino sketch is to detect when the Super Famicom power switch state has changed and either power on the Rpi3 or tell the Rpi3 to shutdown and then remove power from the Rpi3 circuit….
