Circuit emulates mechanical metronome:  8/19/99 EDN-Design Ideas  produces timing signals with a sound like that of a mechanical metronome. IC1 is a 555 timer that oscillates at approximately 3200 Hz. The tw1o 3-kW resistors and the 0.047-?F capacitor set the frequency. IC2 divides the frequency of IC1`s output by 2. IC2 produces a square wave with an exact 50% duty cycle.
