Then you can see how to build a very striking vrometer, which you can use as decorative in the video jukebox.
This great project is a joint development with Gastón, of the famous YouTube channel, LED Projects. We made 2 videos. The first one that follows, presents the VU-meter in protoboard, explaining step by step the operation of the circuit and making all the measurements pertinent. In this way, you will have theoretical bases, indispensable at the time of making this VU-meter.
