So what code allows me to fully turn it 360?
The links you gave me provides no code at all!
You fail to understand what you were told. If you modify the servo per your original instructions it ceases to be a servo and software servo library commands can no longer be used to command the servo to move. You end up with a simple 5vdc motor that has to be controlled via a motor driver and possibly using PWM outputs, and that method has no feedback from the motor to know what position it is at, at any moment in time.
I think what you are asking for is a servo that can be commanded to move anywhere between 0 degrees and 360 degrees and then stop? This isn't possible by modifying typical R/C hobby type servos. Is that correct? Because 360 degree travel and continous travel are two different modes and we would need to understand what you are looking for.
