IoT-Based voice-controlled lighting system / Iqmal Alif Ahmad Taufek

Currently, the most common method of activation for lights and lamps is through the use of wall-mounted switches. These switches however could prove to be troublesome for some individuals especially to those who are disabled or the elderlies as they have limited physical movements to move to the switches. Utilising Internet of Things (IoT) technologies could be very beneficial to create the ability to control and monitor a lighting system via mobile. Thus, the purpose of this project is to assist people with limited mobility with lighting control and deliver added values for general consumers. The objective of this project is to identify the user requirements for the mobile app development, design the mobile application and develop the lighting system and its mobile app. Interview sessions has been conducted to identify the user requirements for this project. An adapted version of the Mobile Application Development Lifecycle (MADLC) methodology was used for the mobile app development. The app prototype was designed using MarvelApp while the mobile application was developed using Android Studio. This IoT-based voice-controlled light is an ecosystem consisting of mobile application and an Arduino-based, Bluetooth-connected lightbulb. The mobile app enables users to connect the mobile phone to the light via Bluetooth, provides voice-control features through vocal commands for the lighting activation and deactivation as well as creating visual monitoring features of the user’s usage patterns in a form of graphics. The app however has limited range of control from the light itself and only allows for switching lights on or off. In the future, both the mobile application is recommended to support data visualisation and illustration feature to improve data digestion among users while the lighting system is recommended to support Red. Green, Blue (RGB) colour gamut. In short, IoT-Based voice-controlled light improves the convenience in a household by providing wireless and meaningful solution to light activation and monitoring with the emergence of IoT.
