इस वीडियो में, मैं आपको दिखाता हूं कि एक Arduino को 16x2 LCD कैसे कनेक्ट किया जाए। आप Arduino Uno के साथ काम करने के लिए alphanumeric (text) LCD 1602A वायरिंग भी सीखेंगे और यह भी कि sketch (program) कैसे लिखें।

In this video, I show you how to connect a 16x2 LCD to an Arduino.
You will also learn wiring the alphanumeric (text) LCD 1602A to work with Arduino Uno and also how to write a sketch (program) .


दो बातें / सेटिंग हमेशा याद रखें:
Following two things / Setting always remember :
1) Board Selection
Arduino IDE App - Tool - Board
2) port with baud rate .

Arduino के साथ LCD Display का काम करने के लिए हमें निम्नलिखित घटकों की आवश्यकता होगी (मैंने उपयोग किया है): -
To make the LCD display work with Arduino we are going to need(I have used) the following components:-
1) Breadboard.
2) Arduino UNO.
3) 16X2 LCD display.
4) connecting wires.
5) power supply come data cable.
6)220 ohm resister .

यहाँ 16x2 LCD Display के पूर्ण पिन कनेक्शन दिए गए हैं:
Here is the full pin connections of the 16x2 LCD display:-

pin 1----------GND---------Arduino GND
pin 2----------VCC---------Arduino 5V
pin 3----------Vo---------Arduino pin 6
pin 4------RW------------Arduino pin 12
pin 5------RS-----Arduino GND
pin 6------data enable Ë -----Arduino pin 11
pin 7--------data 0--------not used
pin 8--------data 1--------not used
pin 9--------data 2--------not used
pin 10-------data 3--------not used
pin 11-------data 4-------Arduino pin 4
pin 12-------data 5--------Arduino pin 4
pin 13-------data 6--------Arduino pin 3
pin 14-------data 7--------Arduino pin 2
pin 15-------BL LED+-------Arduino 5v
pin 16-------BL LED- -------Arduino GND


Code :-
// include the library code:
#include (LiquidCrystal.h)
int Contrast = 70;
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
void setup() {
analogWrite(6, Contrast);
// set up the LCD's number of columns and rows:
Serial.begin(2400);
lcd.begin(16, 2);
}
void loop()
{
lcd.setCursor(0, 0);
lcd.print("Hello Dosto Welcome!!" );
delay(3000);
// print the number of seconds since reset:
lcd.setCursor(0, 1);
lcd.print("To my Channel ** ");
delay(3000);
}


Note :-
#include (LiquidCrystal.h) :- Take code first line or update form
