Uno command interface

I finished my Arduino Uno command interface!
I wrote it with IDE 1.6.4. It should not have any problems (except hardware issues). When using the serial monitor, it shouldn’t matter what line-ending character you have, but you have to use 9600 baud.
Click here to download the zip file, or here to see where you’re downloading it from and what’s in the other three files.
I will post any future updates in this thread. Feel free to make suggestions, I will try to get to as many as I can.
