DIY Metronome

A metronome is a device that produces an audible beat—a click or other sound—at regular intervals that the user can set in beats per minute (BPM). It is typically used by musicians when practicing on a musical instrument in order to play at a regular pulse. Most metronomes have both an audible click sound synchronized with an inverted pendulum swing. This uses the Arduino’s built in timer to calculate when the next beat is to be played, and adjusts the servo motor to swing the inverted pendulum, as well as give the buzzer the signal to make a ‘click’ sound.”
