Abstract: This project presents the design and implementation of a Digital Dual Variable Power Supply with an integrated ESP32-based smart protection circuit. The proposed system delivers two independent and adjustable voltage outputs, making it ideal for powering diverse electronic components, development boards, and prototyping systems. A key innovation lies in the incorporation of an ESP32 microcontroller for real-time monitoring and control, which enhances the safety and functionality of the power supply.Users can define threshold values for both voltage and current via a keypad interface or remotely using IoT-based connectivity. The ESP32 continuously monitors these parameters and, upon detecting any violation of predefined thresholds, activates a relay-based protection mechanism to disconnect the supply, thereby preventing overvoltage, overcurrent, or short-circuit damage.The dual-channel architecture allows simultaneous delivery of different voltages, with digital displays providing real-time feedback on power levels. This makes the system particularly suitable for electronics laboratories, hardware testing environments, and embedded system development. Additionally, the IoT-enabled control offers remote configurability and monitoring, increasing the system's flexibility and usability.
