No i2c device found

I have created a sketch to send Hello World onto LCD. Unfortunately, the LCD is still blinking. After running the scanner program, I have found no I2C device address. I have checked the wiring connections of SDA/SCL lines and have found them alright.

Welcome to the forum

Please post your sketch here, using code tags when you do

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the </> icon above the compose window) to make it easier to read and copy for examination

Please provide details, preferably a schematic, of your project such as which Arduino you are using, how it is powered and anything connected to the Arduino
