60-dB LED VU Meter Schematic Circuit Diagram
Capacitors C4 and C5, proper wiring and correct PCB layout should help to maintain a good degree of noise immunity. For a stereo version of the VU meter, the metering circuits shown here should be duplicated. The power supply has already been dimensioned for a stereo version.
Audio VU Meter – Circuit Wiring Diagrams
This circuit uses two quad op-amps to form an eight LED audio level meter. The op-amp used in this particular circuit is the LM324. It is a popular IC and should be available from many parts stores.
LED Audio VU Meter – Circuit Wiring Diagrams
Note: The total supply voltage must be greater than the reference voltage, but the circuit will work perfectly with supply voltage down to 5V for a reference voltage of 4V or less a low voltage supply is used, RDC and DC+ may simply be joined together. The use of raw DC is only a requirement with supply voltages above around 12V to keep the dissipation of the LM3915 within ratings.
VU Meter | Circuit Diagram
A VU (Volume Unit) meter is a very useful device to show the audio level in audio devices from which a user can maintain a certain audio level and get rid of overloading the output. The figure below shows a schematic diagram of a audio level or VU meter circuit.

Figure 1 Electronic VU meter circuit diagram by LM3914 and LM3915 The main in working of this circuit is LM3914N or IC LM3915N as suitable for your working. Which the external circuit is the same.
LED VU Meter by LM339 – Circuit Wiring Diagrams
The circuit below uses two quad voltage comparators (LM339) to illuminate a series of 8 LEDs indicating volume level. Each of the 8 comparators is biased at increasing voltages set by the voltage divider so that the lower right LED comes on first when the input is about 400 millivolts or
LED VU Meter Circuit Diagram using LM3914 and LM358
The circuit diagram of the VU meter is show in below figure, Working of VU meter Circuit is simple; at first MIC picks up the sound and converts it into voltages levels linear to the intensity of sound. So for a higher sound we will have higher value and lower value for a lower sound. Then these voltages signals are fed to High Pass filter to
