This document outlines the objectives and methodology for a study on controlling home electrical switches through a mobile phone application. The objectives are to determine how to connect Arduino microcontrollers to switches and have them communicate wirelessly with an Android app to control the switches remotely. The document reviews similar existing home automation systems and tools like Arduino, Node.js and React Native. It proposes a conceptual design using microcontrollers connected to switches and a mobile app. Flowcharts and prototypes visualize the system architecture and user interface. The scope is limited to switch control and the methodology involves designing a database to connect the microcontrollers and app.
