PID Programming in RobotC for FTC.
 

So say I want to push a button and this button using PID was to move a encoder to a certain position and since you are using PID it would keep it there. How do you implement PID in robotC code.

The Wikipedia article explains the math behind PID, and even gives pseudo code, and you can get an example of a very basic PIDController here.
