+======LED Command Line Approach======
+The first project for Data Communications by Harry Longwell during the FAll 2013.
+=====Objectives=====
+The purpose of this project was to create make a LED turn on and off using a command line approach.
+=====Procedure=====
+The first step of the project is to connect an LED to the Raspberry Pi's pins, for this project I used pin GPIO 11. This set up is shown in the photo found below.

+The following code will get us to the point were our LED can be turned on, and then off.
+<code>
+sudo su
+echo 11 > /sys/class/gpio/export
+echo out > /sys/class/gpio/gpio11/direction
+</code>
+To turn on the LED we run the following command
+<code>
+echo 1 > /sys/class/gpio/gpio11/value
+</code>

+And then to turn off the LED we run the command,
+<code>
+echo 0 > /sys/class/gpio/gpio11/value
+</code>
