Project Type: Raspberry Pi, Electronic
Kits/Part Source: Raspberry Pi, LED, Jumper Wires, Jumper Wires with female head, Breadboard
Project Source: Make: Getting Started with Raspberry Pi, 2nd Edition by Matt Richardson and Shawn Wallace
In this project I used Linux command line to configure and control the General Purpose Input and Output (GPIO) pins to turn an LED on and off.

The Instructions were pretty clear although the illustrations were pretty crude. A schematic for wiring the breadboard would have been nice too.

The primary purpose of the tutorial is geared towards using the command line so it assumes you have a basic understanding of how to wire an LED to a breadboard.

Using Linux command line the tutorial covered several basic topics:
1. How to run commands as root
2. How to make the GPIO pin available beyond the Linux kernel
3. How to set the GPIO pin to output
4. How to turn the LED on and off
I recommend this tutorial for anyone wanting to learn how the GPIO pins works as an output for electronics.
