Hi, I'm newbie with arduino and I'm trying to use an I2C with a LCD 16x2. For the moment I'm just trying to make a "Hello World" program, but the LCD only displays white squares on the first row. I've tried with different programs/codes that i've seen on youtube, but there hasn't been any difference.
This is the code that I'm using. If someone can help me, I would really appreciate it
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2);
void setup()
{
lcd.init();
lcd.backlight();
}
void loop()
{
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Hello World");
}
And this is what I have
Btw, I'm using the library of Frank de Brabander.
