+- Use a round servo horn and line it up on either of the two possible positions on the pan-tilt base.  You may prefer to mount the servo-horn centered if you are just using the pan-tilt mechanism on a desktop (for example), or you may prefer to mount the servo-horn off-center if you plan on mounting the pan-tilt mechanism on a robot.  The off-center position allows Pixy2 to look over the edge of the base more effectively.

-- Use the servo horn fasteners (found in the servo baggies) to attach the tilt and pan servo horns.

  - The base plate has two hole patterns for attaching the standoffs: a rectangular hole pattern that we showed above and an Arduino hole pattern if you want to mount your Pixy pan-tilt on top of an Arduino.  If you wish to mount your Pixy pan-tilt on top of an Arduino, see below.
