Section 4 - Hooking Up Arduino
This section will go quick!

I have chosen to color code all the jumpers that run between the bread board and Arduino. As you can see on the right, I have connected the yellow jumper to the 5v jack. This goes back to the 5v bus on the breadboard.

Right next to it, I have connected the black jumper to one of the ground jacks on Arduino. This, of course, goes back to the ground bus on the breadboard.

The Power Pins
On the other side of the board we will hook up all the jumpers that go to our digital pins.

The orange jumper comes from our switch. We will hook it up to Arduino's pin 11 and will declare it as an input in our sketch.

The red, green and blue jumpers come from the LED and match the colors we want to display. They get hooked up to pins 5, 6 and 7. We will declare all of them as outputs when we write our sketch.

The Digital Pins
That completes the hardware part of this project. This last image shows it all hooked up. In the next section we will write our sketch and teach Arduino some new tricks!
