Pulling the power to your Raspberry Pi can cause image corruptions & other issues that can damage your Pi! In this article, we will create a small push button that will work as a ‘Safe-Shutdown’ option. We’ll connect it to our Raspberry Pi using the GPIO pins and some jumper wires, and with a few lines of code, we will have our own power switch!

First, we are going to look at a simple way to wire a button to the Pi GPIO connector. We will then write a python script that will shut down the Pi safely. The final step will be to setup the Pi so that the button will work all the time. Let’s Get started!

This method finishes the issues associated with the external power supply leads fraying, braking and in the case of the RCX Motor Mux, shorting to the PCB Components on occasions. Which is not at all advisable!
