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
