===Board Diagram===
-----
Attached is the board diagram created in EagleCad. //Note: This board diagram was created before I knew about the auto-routing tool. Visit the traffic light project page to see a Printable Circuit Board (PCB) ready to be made.//

===Pictures In Action===
-----
Attached are pictures of the Braille Encoder in operation. By reading the dip-switch as a four bit binary number, the corresponding LED pattern matches that of the pattern designated above in the objective section. Hover over the picture for a description.
