Simulate 3x4 Keypad and LCD 16x2 with arduino in proteus

on

COMPONENTS REQUIRED : 



  • ARDUINO
  • LCD 16x2
  • KEYPAD 3x4
  • WIRES

CODE:

                    

#include "Keypad.h"
#include <LiquidCrystal.h>


const int rs = 13, en = 12, d4 = 11, d5 = 10, d6 =9, d7 = 8;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

const byte Rows= 4; //number of rows on the keypad i.e. 4
const byte Cols= 3; //number of columns on the keypad i,e, 3



char keymap[Rows][Cols]=
{
{'1', '2', '3'},
{'4', '5', '6'},
{'7', '8', '9'},
{'*', '0', '#'}
};



byte rPins[Rows]= {4,3,2,A5}; //Rows 0 to 3
byte cPins[Cols]= {7,6,5}; //Columns 0 to 2

Keypad kpd= Keypad(makeKeymap(keymap), rPins, cPins, Rows, Cols);

void setup()
{  
  lcd.begin(16, 2);

  
  lcd.setCursor(0, 0);
     Serial.begin(9600);  // initializing serail monitor
}


void loop()
{



     char keypressed = kpd.getKey();
     if (keypressed != NO_KEY)
     {  lcd.print(keypressed);
          Serial.println(keypressed);
     }
