Going to provide an update on this one. I've selected the following devices:
- Arduino Pro Mini ATmega328P 3.3V
- Microphone module with MAX9814 amplifier
- TP4056 for battery charging/management
- CP2102 USB-UART Bridge TTL Interface
- HM-10 Bluetooth module
- OLED SSD1306 - SH1106 for displaying custom messages based on operation (Nice to have)
I'm trying to accomplish the following: Listen to audio via microphone and transmit to a connected PC via Bluetooth (HM-10).
Question for everyone: Do I have everything I need to accomplish that?
Next question: If you're aware of the best forum to help me understand how to get that operational, please provide links.
I've been perusing forums and seeing some conflicting info on the answer to that.
The other option for me is to just get a micro-SD adapter and save the audio to that but that is plan B - the Bluetooth transmission fully accomplishes my goal.
