This article presents a metronome circuit. To better grasp this principle, you can combine text understandable that circuit. For a more thorough grasp of this principle, you can also learn about the importance of the circuit components, such as: BC109C, CA741 . This circuit uses several amplifier produces an interesting sound effects. Left CA741 connected as a standard instability and generates timing pulses control C1, R2 and VR1. ? Output is fed through C2 to the second operational amplifier and also through the zener ZD1 directly coupled to Q1. ? Hand CA741 is configured as an integrator, its purpose is to distort the output pulse from the first op amp. This ringing effect on the output pulse and gives the circuit characteristics "tick" sound. Output pulse at the first op amp can cause the zener and Q1 for each positive change. 1 k resistor R8 and act it? A low impedance in parallel with the input of the integrator and generates a feature "clock" effect. R8, R7, R9, C3 and C4 may all be adjusted to adjust the sound.
