    So the basic information is all here on the Arduino website: http://playground.arduino.cc/Code/OneWireKeyPad

    Keypad and resistors on breadboard with an Artuino as a Test

    Keypad and resistors soldered to board.

    This wasn’t difficult at all. I’ll see about posting my results, pictures, and more links tonight.

    I used the diagram and schematic to determine which pins I wanted to use then removed the alarm button and soldered a wire to 5V, the 3/4 pin for the keypad input, and 1/2 for the ground.
    From there it was just applying one of the single pin guides to create a voltage divider.

    After that was completed it was just a matter of modifying the code as to take the keypad input where desired and how to handle it.

    If you needed to add more features than just a keypad you could use another micro controller or your preference on hardware and communicate over some communication protocol to allow for many more features to be added. At some point though I feel like it would be beneficial to just make something from scratch than trying to re-purpose the board.

    Thank you for that info. I was considering using a second arduino for keypad entry and then pass the information serially but this should help eliminate extra components and power needs!

    Would it be possible to re-purpose some of the buttons? I was thinking alarm, hour and minute buttons as ones that I won’t need.

    How did you add the keypad and can it disarm the prop once it’s armed? Did you wind up adding another board?

    Thanks!
