# 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.
