Hi there again!
Thnx for your reply, but tell you the truth, I am giving UP =(
Below is my script, please if anyone can tell me, what am I doing wrong? I just want to enter a password, after enetering it, the reed switch goes "on", so whenever I open a door, windows, etc, the "alarm" goes on. All it does, is let's me to enter my password, and reads only once my reed switch. If I add this to void loop (), everything works great, but then my keyboard and LCD want work as I want it to.... Hope you can understand me (sorry 4 my english - Poland ;))
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <Keypad.h>
#include <Password.h>
Password password = Password ("1234");
LiquidCrystal_I2C lcd(0x21,16,2); //PCF8574
const byte ROWS = 4; //four rows
const byte COLS = 4; //four columns
char keys[ROWS][COLS] = {
{'1','2','3','A'},
{'4','5','6','B'},
{'7','8','9','C'},
{'*','0','#','D'}
};
byte rowPins[ROWS] = {6,7,8,9}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {2,3,4,5}; //connect to the column pinouts of the keypad
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
void setup() {
//Serial.begin (9600);
lcd.init ();
lcd.backlight ();
lcd.print ("ENTER PIN");
lcd.setCursor (0,1);
keypad.addEventListener(keypadEvent); //add an event listener for this keypad
pinMode(13, OUTPUT); //led

digitalWrite(12, HIGH); //reed switch for DOOR / WINDOW

// HERE BELOW I HAVA A PROBLEM - ONLY WORKS ONCE, AND ONLY CHECKS PIN 12 ONCE - what am I doing wrong?
