Embedded applications (for example, Arduino, BeagleBone, and Raspberry Pi) make heavy use of GPIO for reading from various environmental sensors (IR, video, temperature, 3-axis orientation, and acceleration), and for writing output to DC motors (via PWM), audio, LCD displays, or LEDs for status.
The control panel allows the end user to manage service such as Apache, SSH and view vital Raspberry Pi/System information over the web.
