This project introduces a modular, plug-and-play power supply platform that supports a wide range of control systems and IoT applications. With multiple regulated voltage outputs, relay-controlled power switching, and flexible I/O compatibility, the platform allows for the integration of interchangeable components and can adapt to different project needs. This system successfully delivers stable 5V, 12V, and 24V power and enables autonomous control of connected devices based on sensor feedback. By integrating a Raspberry Pi, ADC, and programmable relays, it demonstrates reliable operation under load conditions and real-time responsiveness. The platform is scalable and designed to serve as a flexible foundation for future IoT development, reducing the time and cost barriers for student and prototyping projects alike.
