This is only an experimental video and it is not suited to fit in any audio systems.
I tried to make an analog type VU meter similar to those in vintage audio devices.
The Arduino code is available in
arduino IDE file/Examples/Servo/Knob.
This code is actually used to control a servo motor by reading a potentiometer connected to analog input pin A0.
In our project instead of connecting the potentiometer we connect the audio signal from the speaker output of an amplifier through a circuit. That circuit is given in the video.
In the code I changed the servo value to 180, 0 instead of 0, 180. Other wise the servo will rotate in opposite direction.
