AVR Electronic Metronome

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 as programmable beats per measure, measure counting, and distinctive sounds for the first beat of the measure. But the sound of electronic metronomes can be grating. The ATmega16 microcontroller-based AVR Electronic Metronome improves upon the commercial competition with a rich set of sophisticated features and tuneful digital sound options.
