What is LCD Module?

A flat-panel display technology called liquid crystal display (LCD) is frequently seen in electronics including televisions, computer monitors, smartphones, and more. It is composed of two glass or plastic substrates layered with a layer of liquid crystals. The liquid crystals alter their orientation in response to an electrical voltage, either permitting or obstructing light flow. The text and images you see on the screen are the result of careful light manipulation. LCD modules are a popular option for a variety of display applications because of its narrow profile, low power consumption, and adaptability.

Below, we discuss the pins of the LCD module.

Arduino with LCD Module

Introduction

The Arduino microcontroller has completely changed the electronics industry in this digital age. The 16×2 character LCD display is one of the most interesting and useful LCD displays that can be interfaced with Arduino. This post will give a thorough explanation of how to utilize Arduino with a 16×2 LCD display.

Components Required for LCD with Arduino Circuit

We will use these components which are listed below:

• Arduino
• LCD Module 16*2
• Jumper Wires
• One 100K POT
• One 9V Battery
• One Breadboard
• One 220 ohm Resistor

Circuit diagram of Arduino interfacing with LCD

Below shows the hardware connection and circuit connection of Arduino with LCD Module Project.

Code ( How to Print Hello World on LCD Module? )

Copy the code which is written below and upload it to the Arduino.

#include <LiquidCrystal.h>

int seconds = 0;

LiquidCrystal lcd_1(12, 11, 5, 4, 3, 2);

void setup()
{
  lcd_1.begin(16, 2); // Set up the number of columns and rows on the LCD.
}

void loop()
{
  lcd_1.setCursor(0, 1); // set the cursor to column 0, line 1
  lcd_1.print("hello world!"); // Print a message to the LCD.
}
