Abstract:
This paper presents the development of a remote-controlled power switching device utilizing an Arduino Nano, TSOP1738 infrared receiver, and a four-channel relay module. It manages two mains sockets, an AC bulb, and a DC bulb, with the DC circuit supported by a Li-ion battery pack that acts as a backup. The device is encased in a unit with an external power input, controlled via a standard IR remote. The Arduino Nano decodes the IR signals received from the TSOP1738, enabling user interaction. A single button can toggle all outputs, while separate buttons control each output independently. The integrated LCD provides real-time status updates of the outputs (ON/OFF). The Arduino processes the IR signals, correlates them with predefined codes, and sends control signals to the relay module to switch the connected loads. Functionality tests demonstrated consistent voltage switching, stable 5V LCD supply, and a quick 1-second response time, meeting performance expectations. The relay output showed 219V, confirming correct load handling. The 60W bulb's current was slightly above expected, but no overheating occurred, with the relay at a safe 25.3°C. The results illustrate the device's effectiveness, offering a robust method for controlling electrical devices remotely. This design presents an efficient and user-friendly solution for managing AC and DC devices, showcasing the practicality of IR technology in modern home automation.
