This is a small buzzer for the LilyPad system.
Use 2 I/O pins on the LilyPad main board and 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.
20mm outer diameter.
PCB thickness: 0.8mm.
These buzzers are NOT WASHABLE.  Washing these buzzers will damage them.
