Sound Waves

To begin with, play around with the following sound wave app:

Can you discover the relation between the sound you make and the waveform you are seeing?

 

  1. Find 2 alligator clips, a set of headphones and two jumper wires.

  2. Connect them together as prompted.

  3. In the code, add a Buzzer object and change the PLACE to Backpack 1.

  4. Add a Wave object and connect its output (OUT) to the Buzzer note.

  5. Add a Light sensor object and connect its output to  the Wave object length, as you did before

    Explore what happens if you change some aspects of the wave, such as the MIN and MAX values, the TYPE or the LENGTH. Play around with it, what questions can you answer?
