Voice: Recognition System Circuit Diagram

The microphone picks up analog sound waves and converts them into electrical signals.

The voice module digitizes these signals so the processor can analyze them. Voice Recognition System Circuit Diagram

A 5V regulated DC supply is standard for these components. 2. Circuit Diagram Connection Guide The microphone picks up analog sound waves and

You typically enter a learning mode via software or a button on the module. You repeat the command word multiple times (usually 3) until the module confirms success. To build a basic voice-controlled circuit, you will

To build a basic voice-controlled circuit, you will need the following hardware: An Arduino Uno or Arduino Nano is typically used as the central brain. Voice Recognition Module: Common options include the Elechouse Voice Recognition Module V3 or the DFRobot Gravity Sensor Go to product viewer dialog for this item.

Once a match is found, the module sends a specific Command ID (e.g., "1" for "Lights On") over the TX pin to the Arduino, which then triggers a relay or LED. 4. Setup and Training
