I’m trying to get work I2C 2x16 character display QAPASS LCM1602 to work with arduino nero board …
… my code compiles and upload to nero OK but nothing happens in LCD display …
I tried to connect SDA and SCL pins to nero board … and I tried to use A4 and A5 pins…
how I know what pins are really used for my LCD pins ?
If I check those pin with oscilloscope there is no pulses in any pins ??
In code this not compile : LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
but this is OK LiquidCrystal_I2C lcd(0x27, 16, 2);
(as in header file )
I’ll be happy if someone can help me and give me some hints… to solve my problem with arduino

/Impport following Libraries/
//I2C pins declaration
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
lcd.begin(16,2);//Defining 16 columns and 2 rows of lcd display
lcd.backlight();//To Power ON the back light
//lcd.backlight();// To Power OFF the back light
//Write your code
lcd.setCursor(0,0); //Defining positon to write from first row,first column .
lcd.print(" Tech Maker "); //You can write 16 Characters per line .
delay(1000);//Delay used to give a dynamic effect
lcd.setCursor(0,1); //Defining positon to write from second row,first column .
lcd.print(“Like | Share”);
lcd.clear();//Clean the screen
lcd.print(" SUBSCRIBE “);
lcd.print(” TECH MAKER ");
