Hello, everyone. This is my first post in this forum. Sorry if I broke some of the rules.
Moving to the main thing. Not long time ago I bought a “Blue Serial IIC/I2C/TWI 2004 204 20X4 Character LCD Module Display For Arduino” from Ebay. In the internet I found out that it is possible to connect LCD to my arduino board through the I2C that is located on the back side of LCD. Found a code on the internet to display text to LCD, tried to use it- the text were not displayed. After a while found out that each I2C uses different address(0x27 didn’t worked). So I’ve ran several “I2C scanners”. None of them could detect the device.
I have no idea what culd be wrong. Could use some help. Thanks.
The wires are connected:
