Arduino + Sparkfun 12 button keypad part 1

Simple sketch of a keypad interface that uses a password to open a lock or what ever.... Right now all it does is make sounds and flash LED's.

Code for this was borrowed from the Keypad Tutorial here: http://www.arduino.cc/playground/Main/KeypadTutorial and the Password Library here: http://www.arduino.cc/playground/Code/Password and I used the open, error and startup sounds from here: http://hacknmod.com/hack/arduino-keypad-security-system/

Keep in mind that I am still pretty new to the Arduino platform and as such this sketch could probably use some cleanup....

Sketch can be found on my Facebook page here: http://www.facebook.com/note.php?note_id=208615619062

@freeroam10 Sure you would basically just need a function for controlling the servo and just set a call to that fuction in the "code accepted" section.

PS: The link with the sound library is broken, I can't find anything.

How did you make the buzzer play different notes? I have one similar to yours but thay said me that it can just play one note.

I've tried using your code, but it appears that some of the code maybe missing? the last lines are

void resetSound() { int n = 100; for (int vez=0;vez

i love your code is thier anyway that you can mod it so that a servo comes on when you type in the correct code?

Awesome :D

Just got one of these keypads as well. Your code worked like a charm!! Got to start learning more of this stuff :)

1337. Nice password.

Well I had some great comments, then I saw your code. I gotta say, this is the first productive use I have seen of facebook notes.

Only thing I gotta say is that if you get it to work with multiple passwords, you can have a master password, which when entered, would allow you to program in new passwords on the fly. Also you can use the EEPROM to save them, even when the power is turned off.
