Need help! regarding money dispenser using arduino

chandankmr02:
One important thing, I had to make sure that only one note dispensed from the machine at a time.
Any help will be appreciated.

If you send the machine to me full of money (large denominations, please) I will see what I can do with it.

More seriously, I have always been amazed at the ability of my printers to pull single sheets off the stack when I can seldom do that with my fingers. I don't think the printers use contra-rotating rollers.
