Jeff,
It is simpler than it looks.
1: Open the Arduino IDE
2: From the files / open menu in the IDE, navigate to where you unzipped the KD8CEC archive to and open the file named ubitx_20.ino
This will load all of the files into the IDE.
You then need to edit the ubitx,.h file to reflect the display you are using.
This is simply matter of commenting or uncommenting the appropriate lines at he top of the file.
Use the upload button to compile and upload the firmware in the normal way.
