How to make Typewriter Effect LCD I2C 20×4 Arduino? – In this article, I will share the Arduino LCD i2c program code that will display the effect of a typewriter or letter typing with questions. For example, you can see like this one:

It’s easy, for the circuit and basic code you can look at the article LCD 20×4 Arduino I2C Code Basic Tutorial.

Now, i only share the program code. You can copy and paste the program code in your arduino ide code editor and upload it to your board.

Program Code

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x3F, 20, 4);
char array1[] = "  www.chippiko.com";
char array2[] = "Hey, are you sure?";
char array3[] = "Yes, of course!";

void setup()
{
  lcd.init();
  lcd.backlight();
}

void loop()
{
  lcd.clear();

  // Show text 1
  lcd.setCursor(0, 0);
  for (int i = 0; i < sizeof(array1) - 1; i++)
  {
    lcd.print(array1[i]);
    delay(20);
  }
  delay(1000);

  //Show text 2
  lcd.setCursor(0, 2);
  for (int i = 0; i < sizeof(array2) - 1; i++)
  {
    lcd.print(array2[i]);
    delay(50);
  }
  delay(1000);

  //show text 3
  lcd.setCursor(0, 3);
  for (int i = 0; i < sizeof(array3) - 1; i++)
  {
    lcd.print(array3[i]);
    delay(50);
  }
  delay(5000);
}

Done
