Witam
Zaczynam zabawę z Arduino na start poleci kalkulator oparty o klawiaturę 4x4 i lcd 2*16. Znalazłem w sieci projekt kalkulatora i chciałbym dodać drugą klawiaturę która wykonywała by określone działania bez wpisywania np. wciskam klawisz x i do liczby dodaje mi się odrazu 200, naciskam klawisz y odejmuje się 200. Teraz na początek pierwsze pytanie czu tu mam po prostu dodać klawiaturę 8x8 czy to się robi jakoś oddzielnie?

Kod:

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

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

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

 {'7','8','9','D'},

 {'4','5','6','C'},

 {'1','2','3','B'},

 {'*','0','#','A'}

};

byte rowPins[ROWS] = { 0, 1, 2, 3 };// Connect keypad ROW0, ROW1, ROW2 and ROW3 to these Arduino pins.
byte colPins[COLS] = { 4, 5, 6, 7 }; // Connect keypad COL0, COL1 and COL2 to these Arduino pins.

Keypad kpd = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS ); //  Create the Keypad
