I am trying to make a simple arduino project, but the tutorial requires a 2-conductor plug ( https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQjrZl34fJZ7L2cplA93eOylsiywIZa6u3seVnz1SDyPN5RH7f6 )
whiole I only have a 4-conductor plug ( https://vetco.net/spree/products/58711/original/open-uri20160601-21382-1josvf3.jpg ).
How do I use my 4-conductor plug as a 2-conductor plug?
