Your post was MOVED to its current location as it is more suitable.
What made you think that it is a tutorial ?
Hi @pressxx,
On the back of your I2C LCDs, there should be a trimmer potentiometer. Turn it until the actual text/numbers appear on your screen. But if you turn it too much, nothing will be on the screen at all.
Thank you for your help now it's working and I can see the text clearly. Thanks
