fixed it now. i was trying both addresses that "as suggested" previously....then saved at wrong place. see attached please.

Yes that looks correct.
Can you see correct chars on your display now?

No Sorry i cant.

if i open arduino IDE now and program it, it then shows me "Hello World"

I'm very sorry, i didnt mean it that way. My dad has been bragging about flow code since flowcode probably 1.0

I decided i have sometime and wanted to try it out... I'm sure its just something im doing silly.

Does this look right?

Programming successful!


FINISHED

I have now swopped out the arduino boards and changed the wires. And still....

If the wording is wrong after recompiling then the hardware has not been updated with the correct flwochart.
If the address is wrong then there will be a row of squares as the LCD has not ben correctly initilised.
As a sanity check, you can can confim the address is correct by using my I2C sniffer.

This looks bad???

I even tried another LCM1602 Board and sniffed the same result.

Just in case it helps...

My Arduino IDE code sketch that is working on current setup... Maybe it can help?

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

// Set the LCD address to 0x27 for a 16 chars and 2 line display
LiquidCrystal_I2C lcd(0x27, 16, 2);

void setup()
{
// initialize the LCD
lcd.begin();

// Turn on the blacklight and print a message.
lcd.backlight();
lcd.print("Hello, world!");
}

void loop()
{
// Do nothing here...
}
