How to power an audio-level meter / VU meter in a midi-controller project?
I'm building an Arduino-based midi fader controller, and want to also add an audio VU / Level Meter to the enclosure.
The Arduino is USB-powered. … Since the Arduino USB is 3.5 / 5.5 vdc powered, do I need to buy a separate power-supply or wall-wart just to power the meter?
Much appreciated!!! …
