+### Exercise 3
+The SoundCtrCar.java program have four states. Whenever a loud sound is recorded, the state will be change. 
+As it is shown in the video below, the four states are driving forward, turning right, turning left and stopping.
+
+TBD: Add video.
+
+### Exercise 4
+TBD: Add codesnippet of ButtonListener implementation
+
+
+### Exercise 5
+The figure below shows four consecutive claps, measured with the nxt sound sensor.
+The figure shows that the length of claps vary between 85 and 175 ms.

+TBD: Code snippet? Limits: 80 and 200ms?
+
+### Exercise 6
+TBD: Code snippet, video, calibration:-30, raw values are inverted compared to percent readings, PID control and gain choice.
