# Stream Analog input to Serial
We can read an analog signal from a microphone and and write it out to Serial so that we can check the result in the __Arduino Serial Plotter__. To test the functionality I am using a MCP6022 microphone module.

The MCP6022 is a anlog microphone which operates at 3.3 V
We sample the sound signal with the help of the ESP32 I2S ADC input functionality.
### Pins:
| MCP6022 | ESP32
|---------|---------------
| VCC | 3.3
| GND | GND
| OUT | GPIO34
