How to choose
- Digital output (DO) — sensitivity set by the potentiometer, gives a sound/no-sound signal.
- Analog output (AO) — connect to A0 to measure the level and plot it.
Compatibility
3.3V/5V, works directly with Arduino and ESP32; not for speech recognition — that needs a dedicated voice module.
