MATLAB Arduino LCD display System

This program is to connect Arduino with Computer and Display message on LCD send by MATLAB GUI.
Step 1.
Check the port address of arduino and edit the Serial command as required. Default port is COM3.

Upload below program in Arduino UNO or Mega
then Run MATLAB_ARDUINO_LCD .m code

#include <LiquidCrystal.h>

char mtlb_data; //MATLAB Data
int LCDcmd;
int row = 0;
int col = 0;
LiquidCrystal lcd(7,8,9,10,11,12);
//syntax :- lcd(RS,Enable,D4,D5,D6,D7);

void setup() {
// put your setup code here, to run once:
lcd.begin(16,2);
welcome();
lcd.blink();
//lcd.rightToLeft();
Serial.begin(115200);

}

void loop() {
// put your main code here, to run repeatedly:

if(Serial.available() > 0) //1st if open
{
while(Serial.available())
{
mtlb_data = Serial.read();
if(mtlb_data == '#')
{
lcd.clear();
welcome();
lcd.setCursor(1,1);
lcd.print(' ');
lcd.setCursor(0,1);
}
else
{
col++;
Serial.print(mtlb_data);
lcd.print(mtlb_data);
}
}

lcd.setCursor(--col,1);
lcd.print(' ');
lcd.setCursor(col,1);
}
}

void welcome()
{
col = 0; row = 0;
lcd.print("MATLAB and Arduino");
lcd.setCursor(col,++row);
}
