Product Description

Abstarct – This voice-controlled smart home uses an Android app to send voice commands via Bluetooth to an HC-05 module, which communicates directly with an Arduino Uno to trigger specific actions. The Arduino processes these signals to switch lights and a DC fan on or off using transistors as electronic switches, ensuring the components receive adequate power. For garden maintenance, a DC pump is activated to water plastic trees housed in a cardboard model, simulating an automated irrigation system. A servo motor acts as a high-precision actuator to physically open and close a gate upon receiving a “gate open” command. The entire system is powered by a 5V SMPS, providing a stable and consistent voltage across all modules and sensors. This setup demonstrates a seamless integration of wireless communication, motor control, and power management within a miniature DIY environment.
