Arduino + Sparkfun 12 button keypad part 2

Version 3.0 of the Arduino Keypad project I have been tinkering with.. Here I have moved from the full size development board to the actual unit we will be mounting inside an enclosure. I built it on a project board a.k.a. Veroboard, Prototyping board etc. as it was meant to be low cost.

I have also updated the code to include the two remote LED's and an Alarm routine. You can find the updated code here: http://www.facebook.com/note.php?note_id=214492914062

Some photo's of the back of the main board can be seen here: http://www.facebook.com/album.php?aid=43525&id=1029632812&ref=mf

This video was shot and uploaded from a Motorola Droid phone.

@formulaformula1133 actually no, I had them laying around from a pile of samples I got from China years back when I use to run a website that sold LEDs.

The only thing I can think of is you need to get the Keypad and Password Library as they do not come with the IDE by default. Due to YouTube i.e. Google's ridiculous anti-spam techniques I can't post the links in the comment but you can refer to my original video which has the links to the Keypad and Password pages in the Arduino Playground.

Download the library files and install them as noted on the page and that should fix it if this is the problem.

Let me know if this helps...

like those 10mm leds you got : p got that from sparkfun?

hey bro, Do u have the hardware configurations of the keypad to the arduino board. I aint sure how to connect the two devices together bro.

You might look into adding a piezo siren to that. That would make the alarm routine more alarm like.

@rek636 How did you end up getting it to work? I'm having the same problem.

Thanks.

@TwiztedIndian  I just got it to work. I had some how messed up by deleting a letter some where in the sketch.
