Well, I could not get a value other than “0” to show on the display. The only laser pointer I have is the laser “tower” from my Lazer Maze game which I happened to have at home this weekend, so that might be part of the problem. I tried the calibration routine in the lesson, but that did not work. Anyone else having trouble with this one?
I do believe, if I could get the set-up correct, my students would really enjoy this. Could combine this with a robotics lesson in which we are investigating the surface of Mars with the robot representing a Mars rover. The laser could indicate an unsafe area. Would probably want to do the extension lesson to create an “alarm” when the danger area is approached.
