This VU Meter was designed to be used as a desktop instrument with home audio appliances so it has its own power supply. Most of the analog audio media including radio broadcasting stick within 60 dB dynamic boundaries.

This circuit is another name for the VU meter. R5 is used to adjust the current in each LED on IC2 while network R5-R6-P1-R7 sets the reference voltage that determines the full-scale input signal level for IC2. And it is Bar type display driver using 5-Dot LED.

Here are some of the tools you might need. Pin 5 - This is where your signal goes into. The figure below shows a schematic diagram of a VU meter circuit.

The KA2284 KA2285 are monolithic integrated circuit. Which often have a lot of equipment. The shield clearly provides a larger display screen compared to the LED bars and allows the use of LEDs of different colors.

This additional board is shown in Figure 5 and is essentially a shield type board that attaches directly to the original board. The BA61 24 is actually a monolithic integrated circuit which involves a VU level meter driver designed to work with radio cassette tape recorders and other audio products it is additionally efficient at driving 5 LEDs to create a bar- type showcase of input level within the range -10dB6dB. They can display with 20 LEDs on stereo or mono with 10 LEDs for all audio system.

Leds are controlled by Atmega8 microcontroller. It is a logarithmic display driver IC. With 10 LED or 5 LEDs per channel it simple to builds and few parts.

You can also choose in the. But this cycle is not much equipment. Replacing conventional meters with an LED bar graph results in a faster responding more rugged display.

And it is Bar type display driver using 5-Dot LED. Also we can easily build and cheap. Operation of the.

But you can also zero where the start of the voltage measurements occur. The response of the circuit is very fast and it provides beautiful visual representation from audio input signal. KA2284 is Best of stereo audio VU meter circuit with PCB.

LM3916 is a dedicated IC for VU LED meter. The KA2284KA2285 has a wide range supply voltage capacity of 35V-16V but we recommend to use about a 12VDC power supply. 60-dB LED VU Meter Schematic Circuit Diagram.
