IIC/I2C/TWI Interface 1602 16x2 Character LCD Display Module

Fully tested by Karen's e-Shop

Backlit display with potentiometer contrast control

Supports I2C protocol (The I2C interface is pre-soldered ready for use)

Blue with white characters or Yellow with black characters (depending on which option is purchased)

As the pin resources of the Arduino controller may be limited, your project may be not able to use a normal LCD shield after connecting with other devices. However, with this I2C interface LCD module, you will be able to achieve data display via only 4 wires (SDA, SCL, VCC and GND).

Many thanks for looking and don't forget to check out my other items!

INSTRUCTIONS

Recent eBay policy changes prevent me from including links in this listing to external sites where you can find useful information and download tested code libraries and drivers for Windows and the Apple Mac.  However, in compliance with eBay’s new policy, I now provide full details of these links in your order confirmation email, which will be sent within 2 working days of purchase.

Please see the ‘16x2/20x4 LCD Additional Information’ link for further details on this LCD module.  To operate this module, you will need to download the ‘Arduino IDE’ and the ‘16x2/20x4 LCD Code Library’.  

Ensure that the contrast screw is adjusted as required to see characters clearly (Please Note: If this is set incorrectly, characters may not be visible!).

The Arduino Code Library may be used with the following minor change in the init lines:

Some LCD:

LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address (addr, en, rw, rs, d4, d5, d6, d7, backlight, polarity)

Other LCD:

LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address (addr, en, rw, rs, d4, d5, d6, d7, backlight, polarity)

EXAMPLE ARDUINO CODE

#include <Wire.h>  // This library comes with Arduino IDE

// Arduino MEGA 2560 I2C Pins: 20=SDA, 21=SCL

// Arduino UNO and NANO I2C Pins: A4=SDA, A5=SCL

// Import the LCD I2C Library from the link provided in your order confirmation email

// Move any other LCD libraries to another folder or delete them
// See Library "Docs" folder for possible commands etc.

#include <LiquidCrystal_I2C.h>

// Set the pins on the I2C chip used for LCD connections (some versions of the Blue LCDs use I2C address 0x27 rather than 0x3F):
LiquidCrystal_I2C lcd(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);  // Set the LCD I2C address (addr, en, rw, rs, d4, d5, d6, d7, backlight, polarity)

void setup()
{
  lcd.begin(16,2);   // Initialize the lcd for 16 chars 2 lines, turn on backlight
  //lcd.noBacklight(); // Turns backlight off

  // NOTE: Cursor Position: (CHAR, LINE) starts at 0 
  lcd.setCursor(0,0); //Start at character 4 on line 0
  lcd.print("Welcome to");
  lcd.setCursor(0,1);
  lcd.print("Karen's e-Shop");
}

void loop()
{
