Now that the project has been created, you need to change two more settings before we can move on. Go to the Project Navigator panel in the top left area of Quartus and right click on the device ("Cyclone IV E: ..."). Select "Device" from the menu.
Now select the "Voltage" category. Change the "Default I/O standard" to "3.3-V LVTTL". This is essential to do because the panels will not recognize a signal below this voltage.
