They plugged in a light sensor in to sensor port 1.
Then they were not getting any reading on the sensors page or on the robot page. (One group had a 0 on the robot page, one group had a 1.)
As we were looking at it, trying to see what might be wrong, and not finding anything, the sensor started reporting values. I'd guess it was a minute or so?
I came over in both cases because a teacher or high school helper was trying to help the group, then I tried to help, and we saw nothing wrong, fixed nothing, and it just started working eventually.
