Physical buttons that people can push are used as inputs on many different types of devices. Your Photon kit should have a set of 4 push buttons with different cap colors: red, yellow, green, and blue.
In this step, your team will connect a push button to your Photon circuit board using the breadboard.
You'll need these components:
1 push button (could be any color, but use same color as your LED)
2 jumper wires (use two different colors to help identify them)
Follow these instructions explaining how to connect the button. The button can be connected to almost any I/O pin, but connect it to the D2 pin (which will match the wiring diagram).
