There are two routes for assembly: we can either put a laser pointer on top of the servo and tape the button to turn it on, or we can disassemble it and solder some leads on it so it can be controlled by the Metro. 

This wiring is for the first option (non-controlled laser).

This wiring is for the laser controlled by the IR Remote. We are controlling the laser by sending it a voltage from Pin #13.
