You need to show YOUR best attempt to solve YOUR homework problem. We can then help guide you past your current stumbling block.

It will also help us help you if you are a LOT more specific about what you are trying to do. For instance, how is the password being entered? Keypad? Switches? Dials? Voice recognition? Bluetooth?
