I have problem with LCD 16x2 I2C. Everything is connected correctly, code is correct but LCD doesn´t show text. Pins from i2c module are connected: GND - GND, Vcc - +5V, SDA - A4, SCL - A5 (I have Arduino nano 3.0 328p). I used other i2c module but nothing.
LiquidCrystal_I2C lcd(0x27,16,2); //I have used I2C scan program, so address is correct.
Thanks for your advice
