That device is a little USB buzzer. Both the frequency an volume can be controlled. There is even a way to preset simple beeping patterns.

In addition, the Yocto-Buzzer also features two bright leds (one red + one green) and two analog inputs able to read any resistive sensor such as switches, push buttons, potentiometer, reed contact, photo diodes etc....

Long story short, le Yocto-Buzzer is the device you need to get your user's attention, especially if your project is driven by a headless computer.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
