LilyPad I/O Buzzer
This is a small buzzer for the LilyPad system. It uses two I/O pins on the LilyPad main board to create different noises based on the different frequency of I/O toggling. Loud enough to hear inside a pocket but not obtrusively loud.
This is an inductive buzzer meaning that is will act as a short to ground if you are not actively driving it. We recommend you put both I/O pins to LOW (0V) when the buzzer is not used.
