The short led lead goes to gnd.1) Move the wire from pin 9 to gnd. If the led lights, it is wired correctly. 2) If it does not light, reverse the led and try again.3) Use any two opposite corners of the push button contacts, this will always work no matter how the button is oriented. For example, start with the top left contact and call that contact #1. Proceed clockwise and name the top right #2. Bottom right is 3 and bottom left 4. With that numbering scheme, use either pairs 1 & 3 or 2 & 4.If that doesn't get things working, post your code with code tags (the </> icon) and a photograph of your breadboard.
A warning! This last summer, a customer supplied a kit that contained a bag of red LEDS. From China. Some had the long-short leg polarity reversed!Paul
