The proliferation of Internet of Things (IoT) technologies offers transformative potential for urban smart city infrastructure, addressing critical challenges in urban management and sustainability. This paper presents an innovative IoT-based smart city framework leveraging Arduino microcontrollers and ESP8266 modules to enhance various urban services, including traffic management, environmental monitoring, water resource management, and public infrastructure control. We implemented an integrated car parking system utilizing infrared (IR) sensors to detect vehicle presence, with real-time display updates on LCD screens. For environmental monitoring, an MQ2 sensor was deployed to measure pollution levels, providing essential data for air quality management. Smart traffic control was achieved through a system of timers and LEDs (red, yellow, green), optimizing traffic flow and reducing congestion. Water level monitoring and management were conducted using moisture sensors, ensuring efficient water usage and supply. The street lighting system was enhanced with LM358 comparators for day and night detection, promoting energy conservation by automatically adjusting light intensity. Data collected from various sensors were transmitted to the Adafruit cloud via the ESP8266 module, enabling real-time data analysis and decision-making. The Arduino microcontroller served as the central unit, coordinating the various sensors and actuators within the smart city framework. Case studies from pilot implementations demonstrate significant improvements in urban service efficiency, resource management, and environmental sustainability. The findings highlight the potential of IoT technologies to create more responsive, adaptive, and sustainable urban environments. Furthermore, this paper discusses the technical challenges and considerations in deploying such IoT systems, including data security, integration complexity, and the need for robust regulatory frameworks. In conclusion, the integration of IoT with Arduino and ESP8266 modules in smart city infrastructure represents a pivotal advancement towards smarter, more efficient, and sustainable urban living. This research underscores the transformative impact of IoT in modern urban management, paving the way for future smart cities.
