To complete the build of our solar tracker, we need a "viewfinder" for the sun.

Here our viewfinder:

As you can imagine, with this object we can read the light values divided by up/down/left/right

It must be placed on top of the solar panel. The long plastic tab allows you to position it with a certain degree of freedom.

We think that this is the last 3D printed object.

Now we will focus on the circuit building. Stay tuned..
