A VU meter is device that bears a logarithmic scale from -20 to +3 VU, where 0 is equal to 1mW into 600 ohms (sine wave, 1KHz specifically). Further, the meter has a time constant of 300mS, so it’s ...

Finally 7 Vus and 11 patterns working on Arduino Nano and Arduino Pro Mini 3.3 volts. I say finally working because on the Arduino Nano when using Adafruit's Electret Microphone Amplifier - MAX4466 ...
