LilyPad Buzzer

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. They’re even washable!

Note: A portion of this sale is given back to Dr. Leah Buechley for continued development and education of e-textiles.

Resources and Going Further

Check out the activity guide’s Arduino code and examples using a LilyPad Simple Board with the LilyPad Buzzer:


Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

1 DIY

Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.
See all skill levels


Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

1 Electrical Prototyping

Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Customer Comments

  • How about a snap version that you can modify to remove from the circuit when the wearable needs to be laundered?

    lovely.

  • I added support of this part to the Fritzing custom libary.

  • Is it possible to program this speaker to say words only using the tone commands that would create notes? I am fairly new to programming and I do not fully understands the limitations of what i can do with a simple speaker like this.

  • Has anyone actually used 2 I/O lines at different frequencies to drive this buzzer or just 1 I/O line and ground? Is it possible to get higher volume using 2 I/O lines instead of 1+ground?

  • Is this item washable or not? The note says they are not washable then later it says they are. Would you please remove the part of the description that is inaccurate.

  • Could Sparkfun stock that buzzer please?

  • Link to the Datasheet isn’t working. I’d like to know how much power it draws (maybe also say in the main product description)?

  • How do we interface to it to get it to make sound? Thank you.

  • I have order some of them. So i need until they arrive to know the following please.
    could you please give us a schematic example? Could you please give us its datasheet? Could you please show us the voltage range and the transtistor driver?
    thanks a lot.

  • Could you add the LilyPad Simple Board to the All LilyPad Product Sticker Sheet?
