PCB Design:

I did not make it to the make-up class because of another class but I thought I would give it a shot. Here I added a second led to the Hello.echo.44 board by using the spare pins on the processor. I mimicked the setup of the led above it on the board. It seems to need a 1K resistor and since its a type of diode the Anode and Cathode need to be carefully marked. I will mill this out and see what happens. This would be a good board for game where one could led could signify a positive response and the other a negative one.
