The code we have implemented uses three steps; one for driving forward, one for driving left and for driving right. We subtract the two sound levels from the microphones, to see which one of the microphones that registres a higher sound level than the other. We store this new value in a variable and uses it to determine in which direction the robot should drive. If the variable is higher than 7 the robots turns right, if it lower than -7 the robot turns left, and if the value is positive and lower or equal to 7 the robot drives forward. The last step is implemented so that it drives forward when the two microphones registres almost the same level.

### Overall Conclusion ### Overall Conclusion
Though the lab lesson, we have tested sound sensing in different ways, eg. how to only react to a clap sound. Further we have experimented with how the microphone reacts to different distances to a sound source. These test were implemented as a way of controlling the car (robot nxt). It all went rather well, however we ran into some problems regarding the buttonlistener implementation but found a way to solve it. Furthermore, we had a finding we could not explain in regards to measuring sound level at different distances.
