On the 13th, we constructed fabric casings for piezos, which are small buzzers that can emit tones when powered. My casing happened to be in the visage of pac-man, and was constructed around the piezo, which had been removed from its original plastic casing. Today, on the 14th, we tested our piezos, and programmed our Arduino Lilypad microcontrollers to make them play short tunes. I managed to make mine play “hot cross buns,” with a grand total of 236 lines of code. I’m considering using a piezo in my final project; however, I have not completely determined what to create.
