 Interfacing LCD With Arduino for Beginners

LCD

LCD is a very common module which we use in different application and projects. A 16x2 LCD is small LCD which is used to print small and as well as large string. 16x2 means that it can display 16 characters per line.

A 16x2 LCD have 16 pins which are used to display the output string. The pinout of LCD are as follow;

PINS                            FUNCTION

1                                   GROUND 

2                                   VCC

3                                  V0 attach potentiomente out

4                                   RS (Register Select)            

5                                    R/W (Read/Write)    

6                                    Enable

7,8,9,10,11,12,13,14    Data pins

15                                Backlight VCC

16                                Backlight Ground

 

Circuit Diagram

 Connection

• Connect pin 1 to GROUND of Arduino board.
• Connect pin  2 to VCC of Arduino board.
• Place potentiometer on bread board and give GROUND and VCC to it. The center is output pin of the potentiometer and attach it to the pin 3 of LCD.
• The potentiometer is used to adjust the brightness of LCD.
• Connect pin 4 to the pin 12 of the Arduino.
• Connect pin 5 to the GROUND.
• Connect pin 6 to the pin 11 of the Arduino.
• Connect pin 11,12,13,14 to pin 5,4,3,2 of the Arduino.
• Connect pin 15 to 5V and pin 16 to the ground.

Code 

#include <LiquidCrystal.h>

const int rs =12, en=11, d4=5, d5=4, d6=3, d7=2;
LiquidCrystal lcd(rs,en,d4,d5,d6,d7);
void setup() {
  lcd.begin(16,2);
}

void loop() {
 
  lcd.setCursor(0,0);
  lcd.print("DO SUBSCRIBE &");
  lcd.setCursor(0,1);
  lcd.print("LIKE MY CHANNEL ");
  lcd.print(millis()/1000);

}
