It's like sewing a new tutorial by grabbing matching excerpts from other articles. Actually, it's hard to find a paragraph or sentence that is not copied from elsewhere. I think the only original text added here is near to the bottom:

Open the Arduino Desktop IDE then type the codes

and

once the code is successfully uploaded to the board touch the electrode of the transistor with your fingers, this should change the none touch to TOUCH on the LCD indicating that the sensor has been triggered.

and maybe some of the code parts and maybe some of the images.
