# C-3 Connect Button

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](https://docs.idew.org/code-internet-of-things/references/physical-inputs/push-buttons).  The button can be connected to almost any I/O pin, but connect it to the **D2** pin (which will match the wiring diagram).
