Step 12: Connecting the Laser

Before we connect the laser, send: /motor/1/speed 0 (This will ensure this is at a low setting prior to connecting the laser.)

Connect the negative alligator clip to the inside spring of the laser pointer, the insulation around the alligator clip should prevent it from touching the outside of the laser pointer.

Connect the positive lead to the out side casing of the laser pointer. Make sure your on button is taped down to hold it in the on position.

Now send command /motor/1/speed 375

The laser should come on and project what looks like a series of lines or dots.
