) or using a (like the Arduino Nano 33 BLE Sense Go to product viewer dialog for this item. The most common approach for DIY projects involves an Arduino Uno Go to product viewer dialog for this item. connected to a voice module via serial communication. 1. Essential Components

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 Voice Recognition System Circuit Diagram

Most modern modules use a "wake word" (like "Hello Robot") to listen for commands. ) or using a (like the Arduino Nano

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. Setup and Training Most modern modules use a

Note: Pins 2 and 3 are often used with the SoftwareSerial library to keep the main hardware serial free for debugging. 3. How the System Works

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.

The circuit relies on a connection between the voice module and the microcontroller. Voice Module Pin Arduino Pin VCC Power supply (typical 3.3V-5V) GND Common ground RX Pin 3 (Digital) Receives data from Arduino TX Pin 2 (Digital) Transmits voice ID data to Arduino
