In recent years, there has been a rise in the necessity to manage and keep an eye on an automatic system appliance. This project work demonstrated how Bluetooth may be used to operate electric equipment like fans. The system included a Bluetooth module, a relay module IC, as well as additional hardware. To activate and regulate the speed of the chosen appliance (an electric fan), code was transferred from the Arduino to the Bluetooth module in this project via the Android smartphone. The Arduino then communicated with the relay module. The relay driver gave the electric fan instructions, and it subsequently supplies a switch mechanism and an LCD (liquid crystal display) that shows the fan speed. The outcome demonstrated that the work achieved the intended goal. The system is designed to meet the needs of the physically challenged and elderly. Users get increased comfort, risk reduction, and performance thanks to automated processes. Keywords: Android, Arduino, Bluetooth, MIT 2 App Inventor, Relay Module 0150
