An analog VU meter, or Volume Unit meter, is a device used in audio equipment to display the level of audio signal in decibels (dB). This time I will present you a way to make such an instrument yourself, which according to the characteristics does not lag behind commercial devices of this type.
The device is relatively simple to build and consists of several parts:
- Two microamp meters taken from an old faulty tape recorder,
- an operational amplifier ICs (I used TL081, but another similar one can be used),
- some passive elements (capacitors, resistors and diode)
- and a potentiometer that changes the input sensitivity, and serves to calibrating the VU meter.
I also added a peak meter circuit with Arduino, whose function is each time when the signal exceeds the specified level, turns on RED led.

You must have quite a stack of matching metering options by now...
Thanks for going to the trouble of sharing your work.
👍👍👍👍👍
The pin 8 TL081 is not conected according to data sheet.
Analog Vu meter using an Arduino ?
Yes, those meters are often preferred for audio work, because they show a smoothed representation of whatever they are monitoring. So, it is not a downgraded method. He also has incorporated a peak meter, to show clipping of the signal. He has made a very nice piece of equipment, for very little money. I hope that helps your understanding. Cheers!
@@t1d100 yes I already saw the video, great job
