I took one of the audio jacks off my 8X8X8 LED cube circuit board and put it in a pair of headphones for a coworker. It originally was a hardwired cord that got cut in a car door. My coworker just bought a new M/M phone chord with microphone to plug into the headphones and he couldn't be happier!

You could add an analogue pot to control the sensitivity by scaling your offsets. The Arduino map function is good for that.

You could use a timer instead of delay with an interval of 25ms. Leave the mcu to keep cycling round the loop and record the max, mean or average value per timed interval. Reset the value(s) after each interval. Might look a little better.

the code is using a linear scale to drive the VU meter... its a logarithmic scale for audio.....

For me, I would wire the RED LED's into an ESP32 to send commands to the house WiFi so that when the kids got too loud, internet goes down.

Amazing, I think if you add a capacitor on each LED you may have some cool fade effects! but will be costly somehow

How do you pronounce it? I said it the same way I’d say auxiliary.

Great circuit. I'm gonna give it a try. How can I get the circuit to respond to a certain frequency so that I can build an array and make a spectrum analyser?
@aleksandrbmelnikov

Use filter capacitors and blocking diodes to notch each frequency, Use LM3915s or LM3916s to save space. Chain them to stack 20 or more LEDs in each graph.

Incorporate it into a turbo meter on my sports car. It already has a meter of sorts built in but I would have to stare at the dash to read it.

honestly, as nice and simple as that code is, it would be rather slow. to keep it using arduino but to get max responsiveness you could use the map routine to 8 and then use that value to drive the pins directly with PORTX... personally I wouldnt even use the arduino tools and would just run raw c with DDRX and PORTX but I'm a masochist.
