2023 update: here is my recent VU meter build with TFT screen: youtu.be/E2tdxQf2Cbg

A DIY stereo VU meter powered by an Arduino Nano.
It features adjustable brightness and sensitivity and a switch to toggle the peak hold function on or off.

The script can be set to any number of leds and as separate left & right led strips or one led strip that is split into a left and a right part.
