So the software should be considered as a base for your own adjustments and tweakings which is very time consuming. Now I have warned you! Connect one of the 35 cm cable to the light sensor. The cable should run between the beams attached to the motor. Do this before step 55 of the building instructions.
The most crucial part of the robot is the position of the light sensor. It should be positioned approximately 1 mm above the surface. A plastic card should just fit under the sensor without touching it. The files should be downloadable to the brick using the lego mindstorms software:. You don't need the source code unless you want to modify it or if you are just curious. It could be viewed in notepad.
