For that purpose I used a 5mm tick Styrofoam but a cardboard or something like that can be also used. After inserting all LEDs we need to solder all negative leads together and solder a separate wire to each positive lead.

Next we need to solder all electronics components as described in the circuit diagram previously. By my experience, unless you are building a measurement tool, a VU meter needs to: Only a few steps under dB, and stereo vu meter with 80 leds under or dB.

For more information see http: It's based on a program I wrote like a billion years ago on2 balls bouncing off edges but not interacting. When playing with PIC's a few years later I never bothered to port it because it reeked of effort.

Anyhow after moving onto AVR I wrote another version about 3 years ago.

In this project I will show you how to create a custom LED sign that reacts to the loudness of your music, just like a VU meter does. This way I get a small commission: Or you feel super generous and want to use this Amazon link as your Amazon home page.

And do not worry, your purchases are all anonym and the prices are all the same: The stereo vu meter with 80 leds clip is the high end of the comparator chain and lower clip the low end.

You can see the resistors on the left. They provide the reference voltages for the comparators. Using low-tolerance resistors may lead into linearity errors.

Here's the Excel spreadsheet in binary form and the same as gif image: First resistance, resistance of R has been set to 10 kilo-ohms.

All the other resistances are calculated out of these values. The current that flows in the resistor chain is 4.

Then, a voltage drop of 3. That can be created by connecting 10k and 68k in parallel. The resistances could be calculated with a calculator but this is one of the tasks that spreadsheets are for. The last voltage drop from 0.

So, dB level is 0. The LM has input offset voltage of less than 3 mV. If the VU meter would go down to or dB, the offset voltage would prevent it from working.
