Arduino 16×2 LCD Tutorial

    In this article, you will learn how to interface 1602 lcd display with the arduino. You will also learn how to program lcd with the arduino easily.

    If you want to learn how to interface I2C lcd display with Arduino, you can learn here.

    Parts Required

    • 1602 LCD Display [ Amazon ]
    • Arduino Uno [ Amazon ]
    • Jumper Wires
    • 10k potentiometer
    • Breadboard

    Arduino LCD Connections

    Arduino lcd connections

    After connecting it carefully, just download the code below and upload the code to the arduino. In order to work with the code, the code required Liquid Crystal library. No worries, it comes default with Arduino IDE.

    /*
     Demonstrates the use a 16x2 LCD display.  The LiquidCrystal
     library works with all LCD displays that are compatible with the
     Hitachi HD44780 driver. There are many of them out there, and you
     can usually tell them by the 16-pin interface.
    
      The circuit:
     * LCD RS pin to digital pin 12
     * LCD Enable pin to digital pin 11
     * LCD D4 pin to digital pin 5
     * LCD D5 pin to digital pin 4
     * LCD D6 pin to digital pin 3
     * LCD D7 pin to digital pin 2
     * LCD R/W pin to ground
     * LCD VSS pin to ground
     * LCD VCC pin to 5V
     * 10K resistor:
     * ends to +5V and ground
     * wiper to LCD VO pin (pin 3)

    // include the library code:
    #include <LiquidCrystal.h>
    
    // initialize the library by associating any needed LCD interface pin
    // with the arduino pin number it is connected to
    const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
    LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
    
    void setup() {
      // set up the LCD's number of columns and rows:
      lcd.begin(16, 2);
      // Print a message to the LCD.
      lcd.print("    Arduino     ");
    }
    
    void loop() {
      // set the cursor to column 0, line 1
      // (note: line 1 is the second row, since counting begins with 0):
      lcd.setCursor(0, 1);
      lcd.print("  LCD Tutorial  ");
    }
