VU meter or analyzer with microcontroller

Asked By Isabellartd 70 points N/A Posted on - 11/03/2012

Are there any AVR microcontroller experts hanging out around here?

I have an atmel atmega8u2 chip and would like to tie together a VU meter to a display, so that it would display numbers. How would I go around this mini project?

VU meter or analyzer with microcontroller

If what you meant was to imitate the VU display (which is an analog device) by way of displaying of numbers (which is a digital device like 7 segment display), you have to focus on the circuit design that connects to the VU meter. That's because the VU meter reading merely displays a value based on what it receives.

So what you do is to connect your numerical display to the same line as the VU meter. You then program your chip to correctly interpret the value that is supposed to appear on the numerical display.
