How to Connect Mic in Bluetooth Module
Connecting a microphone to a Bluetooth module involves a few steps:
Select a Bluetooth Module with Audio Support: Ensure that the Bluetooth module you have supports audio input. Not all Bluetooth modules have this capability.
Identify the Microphone: Choose a compatible microphone. Most microphones have analog outputs, so you might need an analog-to-digital converter (ADC) if your Bluetooth module only accepts digital input.
Power Supply: Make sure both the microphone and Bluetooth module have a suitable power supply. Check their voltage and current requirements.
Wiring Connections:
Connect the microphone's output to the input of the ADC (if required).
Connect the ADC's output (or directly connect the microphone output if no ADC is needed) to the audio input of the Bluetooth module.
Pairing: Put your Bluetooth module into pairing mode. Consult the module's documentation for specific instructions.t
