The study demonstrates the design of an automated system to assist and provide support in order to fulfill the needs of the physically disabled, sick, and elderly ones in controlling electrical appliances in homes. The heart of the control system is the wireless Bluetooth technology, which provides remote access from a smartphone to a Bluetooth module and then to a control and switching unit. The block diagram of the system was first designed, followed by the circuit diagram design using Proteus software. An algorithm (flowchart) was developed, and the system was programmed using two programming languages. One was the MIT programming language, which is an aspect of the Android programming language for Android app development (for GUI phone usage), while the other one was the Arduino programming language for device controls using the Arduino board. The range of appliance control is the Bluetooth range of 45 meters on a line of sight and not an SMS range, so there is nothing like a network problem during operations. The system was later tested module by module, and all the control operations were working perfectly. The frequency of the Bluetooth is 2.5 GHz (type 2) and covers 45 meters on a line of sight and 10 meters on a non-line of sight with wall penetration. This control system app, thus, is of a low-cost design, easy to install, has a quick response time, and has a user-friendly interface for controlling home electrical appliances.</p> Obianyo O.R.
