How to use LCD I2C

Have you ever wanted to display text in your project? Well, here is a tutorial on how to hookup and use a 16x2 I2C LCD.

Once you gather the materials that are highlighted in the Components and Supplies section, use the circuit image in the Schematics section as a reference to build the basic connection to the I2C LCD. Make sure you put the cables in the correct place / port. At this point you are ready to program the LCD!

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

The program begins with these two libraries. The first is to communicate with the I2C and the second is for the I2C LCD.

LiquidCrystal_I2C lcd(0x27,16,2);

We initialize the I2C LCD library in this part.

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

In the void setup we start the LCD and the light of this.

void loop() {
  lcd.setCursor(0,0);
  lcd.print(" Hello, World!!");
  lcd.setCursor(0,1);
  lcd.print(" 16x2 LCD I2C");  
}

In the void loop, we choose the line to write in setCursor and in lcd.print we write our text. Try not to use the ñ as strange things start to come out.
