o q vc precisa é disto:
#include "Password.h"#include "Keypad.h"
Password password = Password( "1234" );
const byte ROWS = 4;const byte COLS = 4;
char keys[ROWS][COLS] = { {'1','2','3','A'}, {'4','5','6','B'}, {'7','8','9','C'}, {'*','0','#','D'}};
byte rowPins[ROWS] = {2,3,4,5};byte colPins[COLS] = {6,7,8,9};
Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS,COLS );
void setup(){ digitalWrite(13, LOW); Serial.begin(9600); keypad.addEventListener(keypadEvent); keypad.setDebounceTime(250);}

void loop(){ keypad.getKey();}
void keypadEvent(KeypadEvent eKey){ switch (keypad.getState()){ case PRESSED: Serial.print("Digitado: "); Serial.println(eKey); switch (eKey){ case '#': guessPassword(); break; default: password.append(eKey); }}}
putz que moleza hein?

Desculpa aí pessoal mas faltou um pedaço do código, no final coloquem:
void guessPassword(){ Serial.print("Verificando, aguarde... "); if (password.evaluate()){ Serial.println("Abrindo a porta "); // digitalWrite(13, HIGH); //ativa o solenoide delay(2000); digitalWrite(13, LOW); //desativa o solenoide password.reset(); //apaga a senha }else{ digitalWrite(13, LOW); Serial.println("PASSWORD INVALIDA"); password.reset(); //apaga a senha }}
