- A 3.5mm Audio in connector for input.
- Another 3.5mm connector for output to your speakers/stereo.
- 7 Band real time spectrum analyzer (Stereo!) 63Hz, 160Hz, 400Hz, 1KHz, 2.5KHz, 6.25KHz, 16KHz
- Only uses 2 digital pins and one analog.
But see the schematic I can't understand that one audio jack is input and one is output. and I see this schematic use two analog.
Can you help me to understand?

I don't understand how the components are connected together. Can you give me the schematic that wires are connected to all components?
