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!

The Lego Mindstorms NXT is a programmable robotics kit released by Lego in late July 2006. It replaces the first-generation Lego Mindstorms kit, which was called the Robotics Invention System. The base kit ships in two versions: the Retail Version (set #8527) and the Education Base Set (set #9797). These can be used to compete in FIRST Lego League competitions. It comes with the NXT-G programming software, but a variety of unofficial languages exist, such as NXC, NBC, leJOS NXJ, and RobotC. A new version of the set, the new Lego Mindstorms NXT 2.0, was announced in January 2009, featuring an advanced color sensor and other upgraded capabilities. This set is available in the UK, German, U.S and Australian Online Lego shop. The NXT 2.0 sets was officially released on August 1, 2009, and its official product number is 8547.
