Abstract: It is of significant academic interest to develop cheap, dependable and robust protection systems for simple electrical circuitries for both academic and commercial usage. This research paper is intended to propose and implement a prototype overvoltage and overcurrent protection scheme of single phase two terminal passive circuits utilizing the Arduino Uno microcontroller and the Arduino Software (IDE). The proposed scheme would acquire and process conditioned analog input values of voltage and current of a system in real time and the implemented Arduino programmes would monitor whether those values exceed a predefined threshold; exceeding that will trip a relay to protect the system. The scheme would have three major segments that are the current sensing segment, the voltage sensing segment and the relay module and these segments shall be properly interfaced with the Arduino Uno Microcontroller and the load. The scheme is tested on a resistive and a lamp load and an analysis of the obtained data through experimentation on these electrical loads suggest that the proposed scheme is essentially feasible with moderate sensitivity
