The laser pops open with a screw driver. You can see it used 2x1.5v batteries. But it actually runs better at 4.5v.

For the Arduino wiring, attach pins 8 & 9 to the servos. Attach the laser to 5v, but 470 ohm resistor inline before the laser.
Use the code in the attached file to program the Arduino.
Now that it is assembled and done watch it go...
