How To Display Custom Characters On LCD Using Arduino

We all are aware to custom characters used in various display module.Heart,various style of smileys,arrow are the foremost usually used custom characters. Thus during this tutorial we are going to learn how to display custom characters in LCD using arduino uno board. This project is done by using of arduino uno board and 16*2 LCD module.

custom character display

It is assumed that reader know how to interface lcd with arduino and how to install arduino software.We can generate completely different style of custom character using the below pixel array shown in the image. 

Pixel array

custom character shown below that is used in our program to generate the smile type character:

         {

                0b00000,

                0b00000,

                0b01010,

                0b00000,

                0b10001,

                0b01110,

                0b00000,

                0b00000

              };

                0b00000,

                0b00000

              };

void setup()

{

  pinMode(led,OUTPUT);

  lcd.createChar(2, smile);

  lcd.begin(16,2);

  lcd.print(" ProjectsDunia");

  lcd.setCursor(0,1);

  lcd.write(2);

  lcd.write(2);

  lcd.write(2);

  lcd.write(2);

  lcd.write(2);

  lcd.write(2);

  

}

{

 digitalWrite(led, HIGH);       

  delay(1000);

  digitalWrite(led, LOW);

  delay(1000);

}
