MakeBlock - Sound Senor


The sound sensor can be used to control output devices such as motors, lights, sounds etc. Your job is it create a code that uses the sound sensor to activate the motors and make your robot move when it senses loud sounds, and stop moving when it senses quieter sounds.


  1. With your constructed Ranger robot, follow the sample code and upload it to the robot.
  2. Test it.
  3. Now improve the code or make it unique. Perhaps add lights for when it is moving and when it is stopped. How about sound?
  4. Take a screenshot of your code and upload it to FreshGrade. Take a video of your Ranger executing your unique code. Describe what your code does, especially the parts that your group improved or changed.
