I recently bought a cheap VU meter on Amazon, which looks very cool but needs some circuitry to get running. Unlike vintage meters, which can be driven by the audio signal directly, newer (and espe...

LM3916 is a dedicated IC for VU LED meter. Unlike LM3915 which have 3dB step between voltage levels, the LM3916 have nonlinear steps: -20, -10, -7, -5, -3, -1, 0, +1, +2, +3db, just like old school...

Update December 2014: a kit containing all the circuit parts for this project is now available from Jameco Electronics. See the Materials step for det...

The LED VU Meter was the height of late 80s boombox technology. This instructable will build one out on the breadboard. Who doesn't like blinking ligh...

... circuit. Picture of LED VU meter that dances to computer music .... Only thing I would like to do is add an amp to the circuit board with a mic so it dosent have to be connected to a speaker at...

High performance LM3914/LM3915 VU meter circuit projects that widely popular can display with 20 LEDs on stereo or mono with 10 LEDs for all audio system.
