Kevin,

One way would be to put on a move block in the direction you want to go followed by a wait block for light sensor.  The move block should be set for unlimited rotations and the wait block is set up to look for light < 10 (or some number that will eliminate dark blue, etc).

Make sure and calibrate your light sensor for the ambient light on your table.

Subject: [VADCFLL-L] light sensor and loops

We had a new idea for one of our missions but are getting stuck on the coding.  The kids want to use a loop and let the robot roll until the light sensor sees the black line.  We can't figure out how to make it stop moving and go onto the next bit of code at that point.  Any tips?
