Display Serial Data on 16X2 LCD

This program is for Displaying data that Entered on the Serial Monitor of Arduino IDE.

Component required

• Arduino Uno
• 16x2 LCD Screen
• Potentiometer for Contrast Control
• Jumper Wire

Arduino Code

#include <LiquidCrystal.h>

const int rs = 12, en = 11, d4 = 4, d5 = 5, d6 = 6, d7 = 7; 

LiquidCrystal lcd(rs, en, d4, d5,d6,d7);

void setup()

{

  lcd.begin(16,2);

  Serial.begin (9600);

  lcd.print("Myprogmaster!");   

}

void loop()

{

  // when characters arrive over the serial port...

  if (Serial.available()) 

  {

    // wait a bit for the entire message to arrive

    delay(100);

    // clear the screen

    lcd.clear();

    // read all the available characters

    while(Serial.available() > 0) 

    {

      // display each character to the LCD

      char val = Serial.read();

      lcd.write(val);

      Serial.print(val);

    }

  }

}
