Alright, let's go hands on.

The hookup for this guide is very simple. While a button could be used, we will simply touch the alligator clips together to simulate this same function. We'll use a resistor a little later, but for now just connect the alligator clips as shown.

Be careful to not let the BLACK and RED alligator clips touch each other directly. We will be touching other alligator clips together, but never these two.
