I was trying to copy a project to convert an old Atari computer keyboard to work as a USB keyboard. I bought an Arduino Micro instead of an Arduino Micro Pro. The standard micro doesn't have the same pinout numbers as the Micro Pro. The pro lists pins 14, 15 and 16. Are they comparable to any of the other pins on the standard micro? Hope this makes sense. I'd hate to have to buy another board to get this up and running.
