Due Date: Wednesday, October 8, 2008

Description: Piezo speaker, serial output to work with Processing.

Instructions: 

Exercise using a piezo buzzer

1. Connect your piezo buzzer to your Arduino

2. Try the "play_melody" and "sound_serial" programs.

3. If you want to make it quieter, add 10K resistor

4. Make a circuit for a Theremin by adding a photocell

5. Try the "theremin" program.

Assignment this week:

Input output coincidence exercise. Design an artifact where both input and output occur at the same place. Use any combination of your input transducers and output transducers (pot, photocell, FSR, LEDs, piezo, screen). E.g., a ball that changes colors and/or plays different sound/melody depending on the pressure being applied. A stick you can twist to color or sound differently… These are just examples to spark your imagination. Be creative!
