12 button keypad and password

03 April 2013 - 12:23 AM

i have a 12 button keypad http://www.karlssonr...CFVSVMgodv04AEw im wanting to use this for entering a password. just a simple setup that will turn on a light turn on a led once the numbers are put in. then turn off when we i put the numbers in.


if you have look at any of my other post you will see that i am really dumb when i comes to programming with c#. if there is a website site that will walk me through how to do this or something along the lines of this that would be awesome.


i am taking baby steps in this process. which i will try and build the script into some what of a security system.


things would be so much easier if netduino was in ladder logic. lol only kinda of program i can halfway do


thanks for the help

no autodialer and no siren activity
system is active (indicated by blue led - light is 10sec of .5sec on)
buzzer will be active if any sensor is broke

(password can only be changed by holding 1 and # for 5 sec)
(then put in old password then # - then repeat ne password then #)
(if new password is set green led will flash to indicate password change)

security keypad

10 February 2013 - 09:08 PM

listed below is what i am reading on the pdf. page 12. this might not be enough information for you but then again it might.

if the netduino board can not handle that much current would i be able to add resistance to the line in return lowering the voltage so that reads below 20mA for alarm and even lower for standby?


what i am trying to do is make a functional security system using the honeywell key pad with my netduino. i want to keep all the function of the security keypad. so correct me if i am wrong. but with the current listed below if i program the netduino to light up an led with the alarm set and the sensor breaks connection would it work? and not light up the led if the keypad is set for standby and a sensor breaks?







6148 Fixed-Word Keypad 30mA standby/55mA alarm
