When combined with Pixy, the pan/tilt mechanism makes a fun demo — a good “hello world” for Pixy (no Arduino required). The pan/tilt mechanism comes in a kit and requires some assembly.
Note: the servos in the pictures will look different than the ones in your kit. They are functionally identical, so please don't worry!
You will need the following (in addition to a Pixy and a pan/tilt kit):
There are lots of different types of fasteners included in this kit. Refer to the picture below to help you find which fastener we are referring to in these instructions.
You might notice that the later photos show the servo horn with 4.5 holes. Don't freak out - when properly clipped, your horn should have 2.5 holes, like in this photo:
and then all the way to the left:
and adjusting the mounting angle of the horn such that the center of travel has the servo horn pointing downwards. Note, it's OK to move the servo in this way even though it requires a fair amount of force. And it makes a cool sound!
(make sure not to overtighten! Snug is fine)
Grab a two-threaded bracket. If you look really closely, you'll notice that one of its legs is ever-so-slightly longer than the other. Say what? It's true— I don't know why. But you can best see this by looking at the holes in the bracket. One of the holes in centered in its leg and the other hole is not centered, because its leg is slightly longer. Weird.
Take two long 4-40 fasteners and attach two two-threaded brackets to the body as shown in the pictures below. Attach them such that the short legs are touching the body and the long legs are pointing up.
Nice. Now put this assembly aside for now.
It's a bit hard to tell from the photos below, but the shoulder (sticky-outy-bit) of the servo horn should be facing away from the pan/tilt base - not going through the center hole of the base. The servo horn has lots of holes – rotate it until some of the larger ones line up with the holes in the pan/tilt base, then screw it in place.
and then all the way to the left:
You're done!
