Internet of Things and Smart Thinking: Design and Implementation of an Intelligent Lighting Control System Based on Arduino and Android

Abstract

With the popularization of computer technology and the rapid development of internet technology, social life is gradually moving towards intelligence. Concepts that were once theoretical, such as facial recognition payment and smartphones, have become reality, greatly facilitating people's daily lives. In this context, Internet of Things (IoT) technology, as an important component of the new generation of information technology, is promoting the vision of "connectivity of everything" and making our lives more intelligent. Smart home is a typical application scenario of IoT technology. By networking and automatically managing household devices, it significantly enhances living comfort and convenience. However, a complete smart home system is currently costly for ordinary consumers, making widespread adoption difficult. Therefore, this paper focuses on a core subsystem of smart home systems—the intelligent lighting control system—and designs a low-cost solution based on the Arduino and Android platforms. This system allows users to remotely control the on/off status and brightness of home lights through a mobile application, while also featuring a smart night light function that provides temporary illumination for users at night. This paper elaborates on the system's requirements analysis, feasibility study, system design, and implementation process, and tests the system functions. The results show that the system has basically achieved the expected functions and has certain practical value and promotion significance.
