Power LED

Build a Simple Raspberry Pi LED Power/Status IndicatorThis guide will show you how to add an LED power/status indicator to your Raspberry Pi, letting you know when your Pi is powered and when it's safe to unplug.

In this link it teaches you how to add an LED to your raspberry pi to determine if it is on or off. As of 4/6/2021 I am working on combining this and the button for the STEM class Arcade build. LED uses pin 6 for ground and uses pin 8 for positive. Refer to actual arcade drop down tab for diagram of pins.
