Adjusting the contrast of the LCD

After you have wired up the LCD, you will need to adjust the contrast of the display. On the I2C module, you will find a potentiometer that you can turn with a small screwdriver.

Plug in the USB connector of the Arduino to power the LCD. You should see the backlight light up. Now rotate the potentiometer until one (16×2 LCD) or 2 rows (20×4 LCD) of rectangles appear. You can tweak the contrast later if needed.

Once that is done, we can start programming the LCD.

Other useful functions of the LiquidCrystal_I2C library

The example sketch above shows you the basics of displaying text on the LCD. Now we will take a look at the other functions of the LiquidCrystal_I2C library.

clear()

Clears the LCD screen and positions the cursor in the upper-left corner (first row and first column) of the display. You can use this function to display different words in a loop.

#include “LiquidCrystal_I2C.h” LiquidCrystal_I2C lcd(0x27, 16, 2); void setup() { lcd.init(); lcd.backlight(); } void loop() { lcd.clear(); lcd.print(“Monday”); delay(2000); lcd.clear(); lcd.print(“13:45”); delay(2000); }

home()

Positions the cursor in the top-left corner of the LCD. Use

clear()

if you also want to clear the display.

cursor()

Displays the LCD cursor: an underscore (line) at the position of the next character to be printed.

noCursor()

Hides the LCD cursor. The following example creates a blinking cursor at the end of “Hello World!”.

#include “LiquidCrystal_I2C.h” LiquidCrystal_I2C lcd(0x27, 16, 2); void setup() { lcd.init(); lcd.backlight(); lcd.print(“Hello World!”); } void loop() { lcd.cursor(); delay(500); lcd.noCursor(); delay(500); }

blink()

Creates a blinking block style LCD cursor: a blinking rectangle at the position of the next character to be printed.

noBlink()

Disables the block style LCD cursor. The following example displays the blinking cursor for 5 seconds and then disables it for 2 seconds.

#include “LiquidCrystal_I2C.h” LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27, 16, 2); void setup() { lcd.init(); lcd.backlight(); lcd.print(“blink() example”); } void loop() { lcd.blink(); delay(5000); lcd.noBlink(); delay(2000); }

display()

This function turns on the LCD screen and displays any text or cursors that have been printed to the display.

noDisplay()

This function turns off any text or cursors printed to the LCD. The text/data is not cleared from the LCD memory.

This means it will be shown again when the function

display()

is called.

The following example creates a blinking text effect.

#include “LiquidCrystal_I2C.h” LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27, 16, 2); void setup() { lcd.init(); lcd.backlight(); lcd.print(“Blinking text”); } void loop() { lcd.display(); delay(2000); lcd.noDisplay(); delay(2000); }

write()

This function can be used to write a character to the LCD. See the section about creating and displaying custom characters below for more info.

scrollDisplayLeft()

Scrolls the contents of the display (text and cursor) one space to the left.

You can use this function in the loop section of the code in combination with

delay(500)

, to create a scrolling text animation.

#include “LiquidCrystal_I2C.h” LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27, 16, 2); void setup() { lcd.init(); lcd.backlight(); lcd.print(“Hello World!”); } void loop() { lcd.scrollDisplayLeft(); delay(500); }

scrollDisplayRight()

Scrolls the contents of the display (text and cursor) one space to the right.

autoscroll()

This function turns on automatic scrolling of the LCD. This causes each character output to the display to push previous characters over by one space.

If the current text direction is left-to-right (the default), the display scrolls to the left, if the current direction is right-to-left, the display scrolls to the right.

This has the effect of outputting each new character to the same location on the LCD.

The following example sketch enables automatic scrolling and prints the character 0 to 9 at the position (16,0) of the LCD. Change this to (20,0) for a 20×4 LCD.

#include “LiquidCrystal_I2C.h” LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27, 16, 2); void setup() { lcd.init(); lcd.backlight(); } void loop() { lcd.autoscroll(); lcd.setCursor(16, 0); for (int x = 0; x < 10; x++) { lcd.print(x); delay(500); } lcd.clear(); }

noAutoscroll()

Turns off automatic scrolling of the LCD.

leftToRight()

This function causes text to flow to the right from the cursor, as if the display is left-justified (default).

rightToLeft()

This function causes text to flow to the left from the cursor, as if the display is right-justified.

Basic Arduino example code for I2C LCD

You can upload the following example code to the Arduino using the Arduino IDE.

For this tutorial, I used this 16×2 I2C character LCD display, but you can use other I2C LCDs of different sizes as well. This example sketch will display the classic ‘Hello World!’ on the first line of the LCD and ‘LCD tutorial’ on the second line.

Next, I will explain how the code works.

/* I2C LCD with Arduino example code. More info: https://www.makerguides.com */ #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 20×4 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 tutorial”); }

You should see the following output on the LCD:

How the code works

First, the required libraries are included. As mentioned earlier we need both the Wire.h and the LiquidCrystal_I2C library. In the rest of this tutorial, I will cover more of the built-in functions of this library.

*When using the latest version of the LiquidCrystal_I2C library it is no longer needed to include the wire.h library in your sketch. The other library imports wire.h automatically.

#include “Wire.h” // Library for I2C communication #include “LiquidCrystal_I2C.h” // Library for LCD

The next step is to create an LCD object with the LiquidCrystal_I2C class and specify the address and dimensions. For this, we use the function

LiquidCrystal_I2C(address, columns, rows)

.

This is where you will need to change the default address to the address you found earlier if it happens to be different. When using a 20×4 LCD, change this line to

LiquidCrystal_I2C(0x27,20,4);


Note that we have called the display ‘lcd’. You can give it a different name if you want like ‘menu_display’. You will need to change ‘lcd’ to the new name in the rest of the sketch.

// 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 20×4 LCD.

Setup

In the setup, the LCD is initiated with

lcd.init()

and the backlight is turned on with

lcd.backlight()

.

void setup() { // Initiate the LCD: lcd.init(); lcd.backlight(); }

Loop

In the loop section of the code, the cursor is set to the third column and the first row of the LCD with

lcd.setCursor(2,0)

.

Note that counting starts at 0 and the first argument specifies the column. So

lcd.setCursor(2,1)

sets the cursor on the third column and the second row.

Next the string ‘Hello World!’ is printed with

lcd.print("Hello World!")

. Note that you need to place quotation marks (” “) around the text since we are printing a text string.

When you want to print numbers, no quotation marks are necessary. For example

lcd.print(12345)

.

void loop() { 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. lcd.print(“LCD tutorial”); // Print the string “LCD tutorial”. }

If you want to see an example for displaying (changing) variables on the LCD, check out my tutorial for the HC-SR04 ultrasonic distance sensor:

How to find the I2C address of my LCD?

Most I2C LCDs ship with the default address ‘0x27’, but it can be different depending on the batch/manufacturer. If this is the case, you will need to find the actual address of the LCD before you can start using it. On the Arduino website, you can find a simple example sketch that scans the I2C-bus for devices. If a device is found, it will display the address in the serial monitor.

/*I2C_scanner This sketch tests standard 7-bit addresses. Devices with higher bit address might not be seen properly. */ #include “Wire.h” void setup() { Wire.begin(); Serial.begin(9600); while (!Serial); Serial.println(“\nI2C Scanner”); } void loop() { byte error, address; int nDevices; Serial.println(“Scanning…”); nDevices = 0; for (address = 1; address < 127; address++ ) { Wire.beginTransmission(address); error = Wire.endTransmission(); if (error == 0) { Serial.print(“I2C device found at address 0x”); if (address < 16) Serial.print(“0″); Serial.print(address, HEX); Serial.println(” !”); nDevices++; } else if (error == 4) { Serial.print(“Unknown error at address 0x”); if (address < 16) Serial.print(“0”); Serial.println(address, HEX); } } if (nDevices == 0) Serial.println(“No I2C devices found\n”); else Serial.println(“done\n”); delay(5000); }

If you upload this sketch to the Arduino and run it, you should see the following output in the Serial Monitor (Ctrl + Shift + M).

Write down the address you find, you will need it later when programming the LCD.

I2C LCD Basics

This guide is part of our hub of articles on Arduino Displays. This type of LCD is ideal for displaying text and numbers, hence the name ‘character LCD’.

The I2C LCD that we are using in this tutorial comes with a small add-on circuit mounted on the back of the module. This module features a PCF8574 chip (for I2C communication) and a potentiometer to adjust the LED backlight.

The advantage of an I2C LCD is that the wiring is very simple. You only need two data pins to control the LCD. Standard LCDs typically require around 12 connections, which can be a problem if you do not have many GPIO pins available.

Luckily, you can also buy the I2C add-on circuit separately on Amazon, so you can easily upgrade a standard LCD as well.

For a tutorial and wiring diagram for standard character LCDs, please see the following article:

If you look closely at the LCD, you can see the small rectangles that form the individual characters of the LCD. Each rectangle is made up of a grid of 5×8 pixels. Later in this tutorial, I will show you how you can control the individual pixels to display custom characters on the LCD.

Installing the LiquidCrystal_I2C Arduino library

In this tutorial, I will be using the LiquidCrystal_I2C library. This library has many built-in functions that make programming the LCD quite easy.

The latest version of this library can be found here on GitHub or click the download button below.

Make sure that you have this exact library installed and delete any other libraries that have the same name (LiquidCrystal_I2C). Other libraries will probably work as well but might use slightly different names for the different functions.

The LiquidCrystal_I2C library works in combination with the Wire.h library which allows you to communicate with I2C devices. This library comes pre-installed with the Arduino IDE.

To install this library, go to Tools > Manage Libraries (Ctrl + Shift + I on Windows) in the Arduino IDE. The Library Manager will open and update the list of installed libraries.

Now search for ‘liquidcrystal_i2c’ and look for the library by Frank de Brabander. Select the latest version and then click Install.

The library does include some examples that you can use, but you will have to modify them to match your hardware setup. I have included many example codes below that you can use with the wiring setup I have shown earlier.

First I will show you some basic example code and then I will explain the functions in more detail.

How to create and display custom characters?

With the function

createChar()

it is possible to create and display custom characters on the LCD. This is especially useful if you want to display a character that is not part of the standard ASCII character set.

CGROM and CGRAM

LCDs that are based on the Hitachi HD44780 LCD controller have two types of memory: CGROM and CGRAM (Character Generator ROM and RAM).

CGROM generates all the 5 x 8 dot character patterns from the standard 8-bit character codes. CGRAM can generate user-defined character patterns.

For 5 x 8 dot displays, CGRAM can write up to 8 custom characters and for 5 x 10 dot displays 4. For more info see the datasheet.

Custom character example code

The following example sketch creates and displays eight custom characters (numbered 0 – 7). You can copy the code by clicking on the button in the top right corner of the code field.

/* Arduino example code to display custom characters on I2C character LCD. More info: www.www.makerguides.com */ // Include the library: #include “LiquidCrystal_I2C.h” // Create lcd object of class LiquidCrystal_I2C: LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27, 16, 2); // Change to (0x27,20,4) for 20×4 LCD. // Make custom characters: byte Heart[] = { B00000, B01010, B11111, B11111, B01110, B00100, B00000, B00000 }; byte Bell[] = { B00100, B01110, B01110, B01110, B11111, B00000, B00100, B00000 }; byte Alien[] = { B11111, B10101, B11111, B11111, B01110, B01010, B11011, B00000 }; byte Check[] = { B00000, B00001, B00011, B10110, B11100, B01000, B00000, B00000 }; byte Speaker[] = { B00001, B00011, B01111, B01111, B01111, B00011, B00001, B00000 }; byte Sound[] = { B00001, B00011, B00101, B01001, B01001, B01011, B11011, B11000 }; byte Skull[] = { B00000, B01110, B10101, B11011, B01110, B01110, B00000, B00000 }; byte Lock[] = { B01110, B10001, B10001, B11111, B11011, B11011, B11111, B00000 }; void setup() { // Initialize LCD and turn on the backlight: lcd.init(); lcd.backlight(); // Create new characters: lcd.createChar(0, Heart); lcd.createChar(1, Bell); lcd.createChar(2, Alien); lcd.createChar(3, Check); lcd.createChar(4, Speaker); lcd.createChar(5, Sound); lcd.createChar(6, Skull); lcd.createChar(7, Lock); // Clear the LCD screen: lcd.clear(); // Print a message to the lcd: lcd.print(“Custom Character”); } // Print all the custom characters: void loop() { lcd.setCursor(0, 1); lcd.write(0); lcd.setCursor(2, 1); lcd.write(1); lcd.setCursor(4, 1); lcd.write(2); lcd.setCursor(6, 1); lcd.write(3); lcd.setCursor(8, 1); lcd.write(4); lcd.setCursor(10, 1); lcd.write(5); lcd.setCursor(12, 1); lcd.write(6); lcd.setCursor(14, 1); lcd.write(7); }

You should see the following output on the LCD:

How the code works

After including the library and creating the LCD object, the custom character arrays are defined. Each array consists of 8 bytes (only 5 bits are considered). There is 1 byte for each row of the 5 x 8 led matrix. In this example, 8 custom characters are created.

// Make custom characters: byte Heart[] = { B00000, B01010, B11111, B11111, B01110, B00100, B00000, B00000 };

When looking closely at the array, you will see the following. Each row consists of 5 numbers corresponding to the 5 pixels in a 5 x 8 dot character. A 0 means pixel off and a 1 means pixel on. The prefix ‘B’ is the Arduino specific binary formatter.

It is possible to edit each row by hand, but I recommend using this visual tool on GitHub. This application automatically creates the character array and you can click on the pixels to turn them on or off.

In the setup, the custom characters are created with

lcd.createChar(num, data)

. The first argument in this function is the number of the custom character (0-7) and the second argument is the character array that we created.

// Create new characters: lcd.createChar(0, Heart); lcd.createChar(1, Bell); lcd.createChar(2, Alien); lcd.createChar(3, Check); lcd.createChar(4, Speaker); lcd.createChar(5, Sound); lcd.createChar(6, Skull); lcd.createChar(7, Lock);

In the loop, all the characters are displayed with lcd.write(). As the argument, we use the number of the custom character that we want to display.

lcd.setCursor(0, 1); lcd.write(0);
