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

) 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 The microphone picks up analog sound waves and
Most modern modules use a "wake word" (like "Hello Robot") to listen for commands. ) or using a (like the Arduino Nano
You must use the corresponding library in the Arduino IDE to read the recognized IDs and perform tasks. How to Use Voice Recognition Commands With Arduino!
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
