Your contribution cannot be approved because it does not follow the Utopian Rules.
Your tutorial is not narrative enough. The only text you have used was copied from other online sources, for example:
https://www.engineersgarage.com/electronic-components/16x2-lcd-module-datasheet
and
http://www.newark.com/arduino-org/a000066/dev-board-atmega328-arduino-uno/dp/78T1601
I am not sure if I would call this plagiarism but it clearly does not show as much effort as other tutorials for this topic. Please try to be more informative in the future and don't copy phrases from other tutorials.
