MY OLED MODULE IS NOT WORKING......

MY OLED MODULE IS NOT WORKING. I also tried by changing the hardware. But the issue remains the same. What should i Do?

Please surround your code with 3 backticks each (and after pressing the control-T key in Arduino to format it properly). As it is now it is unreadable...
