Using The 16×2 LCD IIC Display Module with Arduino

INTRODUCTION:

This tutorial details the 16×2 LCD IIC module, its functions, and the method to build a simple project using the 16×2 LCD IIC and an Arduino.

THE 16×2 LCD IIC MODULE:

The 16×2 LCD IIC module is a simplified version of a 16×2 LCD. The addition of an IIC circuit enables more accessible communication with the Arduino and fewer wirings.

PIN OUT:

The APDS-9960 has six pins.

GNDGround
VCCPower supply to the module (5VDC)
SDAIIC data pin
SCLIIC clock pin

HOW DOES IT WORK?

The 16×2 LCD IIC module is an output device that displays up to 2 lines of 16-character display. In addition, the component has an IIC module that solves the common issue of messy wiring associated with a typical 16×2 display module. The 16×2 LCD IIC module uses IIC communication protocol to communicate with the microcontroller.

PROJECT – ARDUINO HELLO WORLD LCD DISPLAY

This project will demonstrate how the phrases ‘HELLO WORLD’ and ‘LCD IIC TUTORIAL’ can be projected on the first and second lines of the 16×2 LCD IIC module display, respectively.

PROJECT COMPONENTS REQUIRED:

Arduino Uno Board (1 pc.)
16×2 LCD IIC Module(1 pc.)
Jumper Wires

WIRING DIAGRAM:

The GY-ML8511 module pins are connected to the Arduino Uno board as follows:

CODE:

To use this module properly you need to download two libraries first. These libraries can be downloaded from:

IIC Communication Library Download

Liquid Crystal IIC Library Download

// Include the libraries:
#include <Wire.h> // Library for I2C communication
#include <LiquidCrystal_I2C.h> // Library for LCD
// Wiring: SDA pin is connected to A4 and SCL pin to A5.
// Connect to LCD via I2C, default address 0x27 (A0-A2 not jumpered)
LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27, 16, 2); // Change to (0x27,20,4) for 20x4 LCD.
void setup() {
  // Initiate the LCD:
  lcd.init();
  lcd.backlight();
}
void loop() {
  // Print 'Hello World!' on the first line of the LCD:
  lcd.setCursor(2, 0); // Set the cursor on the third column and first row.
  lcd.print("HELLO WORLD"); // Print the string "Hello World!"
  lcd.setCursor(2, 1); //Set the cursor on the third column and the second row (counting starts at 0!).
  lcd.print("LCD IIC TUTORIAL");
}

PROJECT TEST:

Wire the components to the Arduino as demonstrated in the wiring diagram. Connect the Arduino to a PC and upload the program. The 16×2 LCD IIC Module will display the characters.
