If you want to add beeps, tones or alerts to your Raspberry Pi project, you require a Piezo Buzzer! This mini transducer is small but loud, and can be driven with a 1-20V peak-to-peak square wave. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, stay around 4 KHz. For extra loudness, you can connect both pins to a microcontroller and swap which pin is high or low ('differential drive') for double the volume.
This one plops perfectly into a breadboard and has short legs, so can also easily be mounted on a PCB! Please Note. This item is externally driven, e.g. requires a microcontroller to produce a tone.

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. Also, it's come to our attention that washing these buzzers will damage them. Until we've figured out a solution to this, avoid washing any portion of your project that contains one of these buzzers.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. 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.
