The purpose of this device is to make listening to music easier. It allows you to take your favorite music anywhere you want.

The iPod nano itself uses electrical energy and battery powered energy. Battery power is used to keep the iPod alive and playing music. The click wheel of the iPod uses electrical energy too. It send currents to its grid (electric currents). The conductor is the metal parts inside. When you touch the wheel with your finger it helps complete the circuit. The cover part of the wheel keeps the current from reaching your finger (non-conductor). Under the cover the current is building up.


What sensors/controls are designed into the device?
To change a song of play a game on your iPod you use the click wheel. To use the click wheel only certain materials can make the wheel work. Your finger is an example of a object that will work.
