En el HL no todos cuentan con una llave para ingresar a la casa, esto resuelve un poco este problema.

Armado


Tambien en la red hay varios ejemplos de tipos de armado con diferentes funciones, en nuestro caso usamos un motor DC de una impresora vieja que teniamos.

Usamos lo siguiente:

  1. Motor DC paso a paso (impresora)
  2. Key 4x4
  3. Arduino Mega ADK
  4. Arduino motor shield L293D
  5. Bocina vieja de CPU

Código


El código tambien esta en GitHub

como pueden observar para este proyecto usamos varias fuentes de código y las unimos para obtener nuestro producto que aun le faltan hacer algunas modificaciones.

const byte ROWS = 4; //four rows
const byte COLS = 4; //four columns
//define the cymbols on the buttons of the keypads
char hexaKeys[ROWS][COLS] = {
 {'1','2','3','U'},
 {'4','5','6','D'},
 {'7','8','9','F'},
 {'C','0','H','E'}
};
byte rowPins[ROWS] = {30, 32, 34, 36}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {38, 40, 42, 44}; //connect to the column pinouts of the keypad
Password password = Password( "98125" ); 
//initialize an instance of class NewKeypad
Keypad customKeypad = Keypad(makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS);
