how did you layout the pinout??? so far i was able to plan out:
0keypad
1keypad
2lcd
3lcd
4lcd
5lcd
6keypad
7keypad
8keypad
9keypad
10keypad
11lcd
12lcd
13buzzer
keyswitch wired between battery and arduino to set ready mode
enter code followed by pound to arm
enter seperate code followed by pound to disarm
any other presses decrease time by ten sec.
this is my first project as well. i have the code portion covered
but im lacking in the knowledge of what pin can do what.
is it possible to wire the keypad to the analog pins to free up some of the digitals??? id like to add a flashing rgb led so thats another pin there...
