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.
Please note: 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. This buzzer is rated for 2.5V to 4.5V operation (3.6V typical), so using it at 5V is not recommended. Also, this buzzer board is not waterproof! Unlike other LilyPad components, this buzzer will be damaged if washed.
LilyPad is a wearable e-textile technology developed by Leah Buechley. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. Most are even washable — though this buzzer board is not.
