Help with breadboard

Hello all, I have no clue what I am doing when it comes to using a breadboard and raspberry pi. I found a DIY for reptile enclosure that I am building it is located here: http://www.raspiviv.com/raspberry-pi-vivarium-controller/fans

I am comforable with the code etc, but unsure what to do with the breadboard. I need 2 5V computer fans hooked up to the breadboard which will be automatically activated when humidity hits a certain level. I understand that this is laid out but the examples are chinese to me. Any advice on how to see exactly how the wiring needs to be besides what has been provided? Thanks in advance!

You have to transfer your PI GPIO to the breadboard with a cable or a cobbler or wires.

I prefer a cobbler because you have the number of the gpios. If u accomplish that then it is very easy to wire them
As i can see to the tutorial u use 3 sensor.
1.Black cable of the sensors goes to Pi GPIO GND pin
2.Red cable of the sensors goes to PI GPIO 3V3 pin
3,Yellow cable of the sensors goes to PI GPIO02,GPIO03,GPIO04 pins
Wire the sensors to ground (black - pin 6) 3.3v (red - pin 1) and WiringPi pins 7, 8, 9 (yellow - pins 3, 5, 7)

You must also find which Pi the tutorial use and what do u have because there maybe some differences to the GPIO. Models B+ and 2 have more pins.
