A simple VU meter realized with only mechanical typical items, as screws or nuts, but powered by Arduino!
I have always been attracted by VU Meters, in fact at home I had designed a system to listen to music using my father’s old A/V mixer equipped with 2 VU meters, the first one for the left audio channel and the second one for the right audio channel. One day, suddenly, the mixer stopped working, so I decided to make a VU meter myself using Arduino…
