# Stream Analog input to A2DP Bluetooth  

We can read an analog signal from a microphone and and send it to a Bluetooth A2DP device. 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.
