Sound Sensors

These sensors respond to the amount of sound (it can measure iup to 90dB). The output on the screen is a percentage of the maximum sound it can detect. You could use this to make your robot react to a clap or other loud noise. Remember that the competition is a noisy place, so this type of sensor may be easily fooled by other noises.

The example below will make the robot move backward if there's a loud enough noise.
