Story

Hello friend welcome to “Techno-E-Solution” Today, we are going to interface 16×2 LCD with Arduino UNO.

To interface LCD to the Arduino we need Liquid crystal library. The LCD module is use liquid crystal to print visible text on display, Mainly this display are used for DIY project. Friends as you know 16×2 LCD comes with 16 columns and 2 rows hence it's called as 16×2 LCD Module, In this display you can print maximum 32 characters. This LCD module is very general purpose LCD, we can use this LCD in our project very easily. This LCD comes with 16 Pins to connection I provide the pinouts of the LCD See below. The LCD has many types like 8×1, 8×2, 10×2, 16×1, 20x4 etc. This display comes with blue or green backlight, with white or black text. This display has 16 pins, The first six pins are used to control contrast of the display and 7 to 14 means 8 pins are Data pins and last to pins are used to control backlight. If you want to make this project on PCB I will provide PCB layout of this project just Comment to provide PCB layout. So friend now I'm going to interface LCD with Arduino. Let's get started..........

  Hello friends welcome to "TECHNO-E-SOLUTION"
  Here, is a code to interface LCD with Arduino
*/

#include <LiquidCrystal.h>

const int rs = 12, en = 11, d4 = 6, d5 = 5, d6 = 4, d7 = 3;
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);

void setup() {
  
  lcd.begin(16, 2);  // set up the LCD's number of columns and rows:
  
  lcd.print("   16 X 2 LCD   ");  // Print a text to the LCD.
}

void loop() {
  
  lcd.setCursor(0, 1);  // set the cursor to column 0, line 1
  lcd.print(" LCD + ARDUINO  ");
}
