Bellow is more documentation of my Analog Output Lab. I though it would be nice for future reference to have a better angle of the wires and Arduino. Also it was important to make interact real people with my chicken fighters. I hope you enjoy:

My wires:

Here is the code:

/*

Servo control from an analog input using the Arduino Servo library

 

This example code uses the Arduino Servo library which comes packaged with the Arduino software.

 

In order to make this work, you must include the Servo.h library file, create an instance of the Servo object, 

attach a digital PWM pin to the Servo object, and then write an analog value to the Servo object to set its 

position.

 

The difference between using the Servo library and the older method of pulsing a digital pin is that the library

handles a lot of the work for you. You no longer need to figure out the translation between pulse length and position. 

You now can simply specify the angle you’d like your servo to be at and it will turn to that position.

 

Please note, unlike the older pulsing method you MUST use a digital PWM pin or it will not work.
