I had no problems following the directions but the illustration indicated I needed to setup the LED with pin 25. The project doesn't do anything with the LED.

Easy but the project assumes you have a basic understanding of breadboarding a circuit.

Momentary Push Button breadboarded to Pin 24 of the Raspberry Pi

The tutorial covered how to:

1. Turn Pin 24 into an input

2. Setup the Pi to read input from the push button. If setup correctly, zero indicates the button is not pushed and 1 Indicates the button is pushed.

Although this is a quick and simple project, this is necessary knowledge for making the Pi work with a breadboarded circuit.
