 Moppy was built for Arduino UNO, though it should work just fine on most
 Arduinos.  The pins are connected in pairs to floppy drives as follows: Even
-pins (2,4,6...) are connected to each drive's STEP pin (pin 20) , the matching
-odd pins (3,5,7...) are connected to the each drive's DIRECTION control pin
+pins (2,4,6,...,A0,A2) are connected to each drive's STEP pin (pin 20) , the matching
+odd pins (3,5,7,...,A1,A3) are connected to the each drive's DIRECTION control pin
 (pin 18).  So the first floppy would be connected to pin 2 & 3, the second floppy to 4 & 5, and so on.
 
 Make sure you ground the correct drive-select pin (pin 12), or the drive won't respond to any input (just connect the drive-select pin on the floppy to the pin directly below it).  You can tell when you have the right drive selected, because the light on the front of the drive will come on.
