The goal of this lab session is to experiment with the **NXT Sound Sensor** and build a sound controlled robot.
We do this through the exercises described in the [lesson plan] (http://legolab.cs.au.dk/DigitalControl.dir/NXT/Lesson3.dir/Lesson.html).
The goal is to make the LEGO robot follow a black line and stop at the end of the line when the car drives into a goal zone - a green rectangular piece of paper at the end of the black line.
