The servo is definitely working. I'm 99% positive the problem is my programming.

When the servo is plugged in and the robot is enabled, there's no reaction. If I switch the way the servo is plugged into the PWM it will lock into a position and attempt to maintain that position. It still does not react to my button pushes though.

A properly operating servo will "lock into a position and attempt to maintain that position." It sounds like your servo had been connected backwards before.

You should probably show us the code that reads and reacts to button pushes.

Here's the code. It is command based and a bit too inconvenient to put in a post so I uploaded it to github.

The problem areas are in the subsystem GateServoTwo and the commands CloseGateTwo, OpenGateTwo, and the command group GateTwo.

Where are you reading the button? I don't see where in the code the GateTwo command is invoked.

The association between the button and the command is in the OI.cpp in lines 37 and 38.
