LCD 16x2 Interfacing with Arduino (Text Displaying)

 

LCD (Liquid Crystal Display) 16x2 is used to display ASCII characters. LCD is very impressive and attractive for any Arduino Project or any controller project. We can display direct text (ASCII) Alphabets and digits on it and can display function type values also, simply there are techniques to display your text on LCD. Here we are displaying just simple text to show interfacing and simple steps in Arduino IDE coding. Arduino IDE also has built-in examples in which you can modify but have understanding when you want to use in your own project and may this built-in example not fit for that. Here we are giving you understanding.

Application:

Display Characters in ASCII format

Display text, digits, etc.

Components:

Arduino Uno

Connectors

Arduino IDE (Compiler software)

Computer for programming

LCD 16x2

Pot-meter: Use to control the contrast of LCD

Circuit:

Connects are given very clear in circuit diagram but if you have any query then you can ask me.

Coding:

/*LCD D7 to D4 - Arduino Uno Pin 2-5

LCD EN - Arduino Uni pin 6

LCD RS - Arduino Uni pin 7

LCD D3 to D0 and RW and Vss Ground connected

Vdd with Vcc and VEE use to control the contrast

// include the library code:

#include <LiquidCrystal.h>

// LCD PINs

const int rs = 7, en = 6, d4 = 5, d5 = 4, d6 = 3, d7 = 2;

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

void setup() {

  // Initialize LCD 16x2

  lcd.begin(16, 2);

  }

void loop() {

  // set the cursor to column 0, line 1

  lcd.setCursor(0, 0);

  // print the number of seconds since reset:

  lcd.print("ElektronicGarage");

    delay(100);

  lcd.setCursor(0, 1);

  lcd.print(" Fayyaz Hussain ");   delay(100);
