A 5V regulated DC supply is standard for these components. 2. Circuit Diagram Connection Guide The circuit relies on a connection between the

The microphone picks up analog sound waves and converts them into electrical signals. connected to a voice module via serial communication

LEDs, relays (for high-power appliances), or a buzzer to confirm commands.

Building a voice recognition system circuit is usually done in one of two ways: using a (like the Elechouse V3 Go to product viewer dialog for this item.

Usually included with the module, but some circuits use an external earpiece or computer microphone.
