Overview
The piezo can be connected to digital outputs, and will emit a tone when the output is high. Alternatively it can be connected to an analog pulse-width modulation output to generate various tones and effects.
Grove - Buzzer is a simple yet enjoyable twig to use. It can output noise at a volume over 85 dB and is integrated with Grove interface, which makes it easy to connect and experiment by just plug & play. It is a perfect add-on for all kinds of Arduino projects and human-machine interfaces.

Hackster is a hardware creation community and since last february has been organizing Hardware Weekends with hackathons all over US. On Saturday and Sunday June 26th and 27th it's coming back to New York City for the last time in 2015. This hackathon is focused on open source hardware and the maker communities across America: all ages and skill levels are welcome (Children under 16 should be accompanied by an adult.) Here's a short video from their event taking place at Kickstarter offices last month and some pictures past events. Hackster is providing all the food, tools, soldering stations, 3D printers, workshops and gear (Arduinos, Particle, LinkItOne, Intel Edison, Pebble, Smart Things, and software from Autodesk, Azure and more!) $1000 Grand Prize from Microsoft and Arduino Zeros from Hackster! Register your participation here. It's going to be a lot of fun!
