Tuliskan program dibawah ini:

#include <LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);

#include <Keypad.h>
const byte ROWS = 4; //four rows
const byte COLS = 4; // four columns
char keys[ROWS][COLS] = {
{'7','8','9','/'},
{'4','5','6','x'},
{'1','2','3','-'},
{'C','0','=','+'}
};
byte rowPins[ROWS] = {A0, A1, A2, A3};
byte colPins[COLS] = {10, 9, 8, 7};

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

void setup() {
lcd.begin(16, 2);
}
void loop() {
// put your main code here, to run repeatedly:
char key = kpd.getKey();
if (key!=NO_KEY){
lcd.print(key);
}
}
