Nano & LCD 0802A & Surenoo I2C-B 2X8P Blank Display [contrast not set]

[fendt728]

Hello,

i bought a Arduino Nano and a LCD Display, but then I realised I bought it without I2C so I bought a I2C Module the Surenoo I2C-B 2X8P, but the Display light is on without the text.

I hope you can help me.

Thx

Arduino Nano: Nano

LCD Display (Note: It is the second one (blue 0802A)): LCD Display

I2C Module(Note: It is the second one): I2C Module

Code:

#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 8, 2);

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

  lcd.setCursor(0, 0);
  lcd.print("Test");
}

void loop() {
}

Run I2C_Scanner.ino and verify if module address is 0x27.

The scanner confirms 0x27

Have you tried adjusting this pot?
