So the IC of choice is one of LM3914 / LM3915 / LM3916. Resorting to al analog circuitry without any Arduino microcontrollers as that would be another project for another time. So in order to make this VU meter, I’ll be I’ll also be having some video footage for a change. I’ll make a list of parts, buy them and assemble the circuit. I made 3 of these for a Museum’s exhibition about a month ago with schematics from some book or article that I’ll be including in the end, but for this project, I want to dig into selected IC datasheet.
So I searched Instructable for a 20 LED VU meter or some sort but with no result. But even for us, it can be dull and having that extra more is much cooler and doesn’t cost that much more. So it’s popular by these 10 LED ones but for professionals, those don’t give much resolution. I’ll show you how datasheet is a very strong and viable tool to work with on your project instead on relying on others(projects).Įveryone knows about a VU meter and for an electronic enthusiast is like an amplifier and a speaker, everyone makes one because it’s fun to look at and you can use it by your radio or amplifier speaker combo.

Its clean interface makes it very easy to use, while the customization options help it blend with the desktop theme or background.This instructable, I’m going to show you how to make a nice 20 LED VU meter with minimal parts and effort. VU Meter is designed with simplicity in mind, aiming to accurately display the level of audio signals processed by your computer's sound card. Displays an old volume unit meter on your desktop Optionally, you can instruct the application to stay on top of all the other opened windows, which enables you to overlay it on top of any audio processing program and monitor audio levels.

The meters can be displayed either horizontally (side by side) or vertically (on top of each other) and the response time (the duration of a full swing across the gauge) can be changed from the default value of 300 ms to just 150 ms. There are various other settings that you can configure.
VU Meter enables you to change the color of every element for each meter, starting with the background and continuing with the pointing needle, the arc of the meter, major and minor lines or the displayed text. Various customization and configuration possibilitiesīy default, the meters are displayed in black and white, but you can fully customize their appearance via the 'Options' window. This comes in handy when listening to audio streams that were recorded at a lower value. Right-clicking anywhere on the main interface reveals a menu that enables you to allow the variable maximum value, as well as reset it to 0, 20 or 40. It displays a real-time representation of the audio signal level for both the left and the right audio channels. The application is similar to a sidebar gadget, since its interface does not take much desktop space and you can move it around wherever you want to. It imitates the volume unit meter of an old stereo, displaying volume indicators on your desktop. VU Meter is an interesting application that acts like a virtual audio level meter.
