If you learn a music instrument, definetely you know about metronome. A metronome is a device musicians use to maintain tempo. It generates a clicking sound at a steady rate that is set the user. Traditional mechanical metronomes use a windup spring and a dual-pendulum arm to produce the clicks. Michael Kirkhart from U.S. has design Electronic metronomes that offer additional functionality, such
