Abstract The automation system described in this project leverages the power of Bluetooth wireless communication to control the bulb and fan. The system utilize readily available components such as Arduino Uno, HC-05 Bluetooth module, and 4-channel relay module, it provides a cost-effective solution for creating a smart environment. The Arduino Uno acts as the central controller, receiving commands wirelessly via the Bluetooth module and subsequently controlling the power supply to connect devices through the relay module. This allows users to remotely turn on or off devices such as bulbs and fans, providing convenience and energy efficiency. The measured response times for turning on/off the fan and bulb in the automation system were found to be 15.47 μs for turning on the fan, 15.20 μs for turning off the fan, and 16.27 μs for turning on/off the bulb. These results indicate that the system is highly efficient and reliable in controlling the devices. Future enhancements can include the implementation of security measures to protect against unauthorized access and integration with other smart devices. The Bluetooth automation system showcases the potential for creating affordable and customizable automation solutions using easily accessible components
