Hi. We’re currently working through the Castle Crasher STEM Lab.
Having used the optical sensor in the Treasure Hunt Lab, I have two immediate observations / questions:
- The mounting of the optical sensor facing downwards toward the floor is odd - all the videos depict it facing up.
- The challenges and activities in Lessons 4 and 5 seem to not even necessitate the use of the optical sensor. I was expecting another level of complexity (such as only sweeping the blue balls off the field) which was just not there. It’s basically the same thing as before, just with more bucky balls.
If I’m wrong about the above, please show me how.
