This is a sample project for receiving audio data using ESP32 microcontroller. The chip has a built-in 12-bit ADC which is used to process the analog audio from the external microphone module in real-time. The received messages are displayed on the attached OLED display
- NodeMCU-ESP32
- OLED SSD1306
- MAX9814 (also works with KY-037, KY-038 and WS Sound sensor)
