Arduinóhoz van egy projektem (lent) és ha bírom a beállított kódot, ki is írja, hogy érvényes, de a kimeneten nem ad áramot, mi lehet az oka?

#include <Password.h>

#include <Keypad.h>

Password password = Password( "1234" );

const byte ROWS = 4; // Four rows

const byte COLS = 3; // Three columns

// Define the Keymap

{'1','2','3',},

{'4','5','6',},
