Module I2C

Code Arduino :

#include "Wire.h" // For I2C
#include "LCD.h" // For LCD
#include "LiquidCrystal_I2C.h" // Added library*
//Set the pins on the I2C chip used for LCD connections
//ADDR,EN,R/W,RS,D4,D5,D6,D7
LiquidCrystal_I2C lcd(0x27,2,1,0,4,5,6,7); // 0x27 is the default I2C bus address of the backpack-see article
void setup()
{
   // Set off LCD module
   lcd.begin (16,2); // 16 x 2 LCD module
   lcd.setBacklightPin(3,POSITIVE); // BL, BL_POL
   lcd.setBacklight(HIGH);
}
void loop()
{
   lcd.home (); // Set cursor to 0,0
   lcd.setCursor(5,0);
   lcd.print("axeled"); // Custom text
   lcd.setCursor(4,1);
   lcd.print("YouTube"); // Custom text
