If you're following along with a Raspberry Pi, we're going to use a T-Cobbler Plus for the IO Basics Projects. This add-on prototyping board lets you easily connect a Raspberry Pi (Raspberry Pi Model Zero, A+, B+, Pi 2, Pi 3) to a solderless breadboard.
You'll need to make the following connections:
- Pi GND to a common ground rail.
- Pi GND to one side of the momentary button.
- Pi Pin 12 to the other side of the momentary button.
Next, proceed to the Python Setup Page of this guide.
