Tak to zrozumiałe, czy dobrze?

Kod:

#include <Keypad.h> //Header file for Keypad from https://github.com/Chris--A/Keypad

const byte ROWS = 4; // Four rows
const byte COLS = 8; // Three columns

// Define the Keymap
char keys[ROWS][COLS] = {

{'7','8','9','D','E','F','G','X'},

{'4','5','6','C','H','I','J','Y'},

{'1','2','3','B','K','L','M','Z'},

{'*','0','#','A','N','O','P','O'},

};
