Exploration into a physical manner to notify a user of an incoming phone call. A small electronic motor connected to a solenoid valve system controls inflation and deflation of a bright-colored ballon.

The parts originally came from a Blood Pressure Monitor purchased from Amazon.com for around $30.00. The casing disassembled pretty quickly and the 6V DC motor was running straight off the arduino 5V pin, sufficient for testing.
