Design and Construction of Voice-Controlled Home Automation using Arduino

Abstract

System automation has been widely researched in the twenty-first century due to its essential role in daily life. The fundamental  advantage of an automated system is its ability to reduce human stress and minimize errors. Over the past few years, there has been a  swift shift from traditional switches to switches equipped with remote controls. Currently, the presence of conventional wall switches  distributed around the house poses challenges in terms of use, especially for individuals who are elderly or have physical disabilities. Due  to technological advancements, mobile smartphones are now affordable for all individuals. Android devices are becoming equipped with  applications that aid in multiple ways. Another new technology is the Google speech recognition APIs, which enable voice-based system  command and control. This study demonstrates the implementation of voice-controlled home automation using the Arduino Uno  microcontroller. Users of this system will be able to exercise full authority over every domestic device through spoken commands. The  control circuit consists of an Arduino Uno microcontroller that receives and interprets voice commands from an Android smartphone  equipped with the corresponding application. While the Bluetooth module shares signal data after establishing a wireless link between  the microcontroller and the smartphone, the relay regulates device switching.
