This is a tool for the classroom if you'd like some quiet time. Will the sound in the room is low, the puppy walks left to right. When it's midrange, he pauses, and if it's noisy, he falls! Oh no. You can recalibrate to the right noise level in your class by changing the numbers in the 'if loudness > 30' and 'if loudness > 50' blocks to larger numbers.
