Day by day technology is growing rapidly in the form of smart gadgets and today’s high-tech world has brought up many new and complicated issues that require sterilization for the basic principles of academic integrity and tests. The ability to balance the purity and fairness of assessments has directly corresponded to the increase in state-of-the-art technical advancements of such tests. Through the new strategies and increased use of smart gadgets, educators and administrators must now confront the immediate imperative to successfully navigate minimizing the unprecedented forms of cheating that have emerged in parallel with the advancements in smart devices. Therefore, it becomes a complex and multifaceted task to monitor the process to protect the academic integrity and fairness of students’ evaluation, which has evolved from a straightforward monitoring of cheating into an important information control with new approaches and heightened concern necessary. A low-cost system that acts as a solution to cheating by interfacing with Arduino is developed in this study. In other words, one aims to inhibit any external signal exchange between the devices in the exam room through the application of RF interference. The Authors decided to use an Arduino microcontroller, RF signal detectors, and jammers to detect unauthorized communication signals and disable them during its activity. For instance, in the suggested system a scan for radio frequency signals is performed every ten seconds and if any are detected the jammers are turned on to ensure that unlawful communication does not take place. This approach optimizes system effectiveness and energy consumption and it ensures perpetuated vigilance. These detectors feed information into the Arduino microcontroller, which serves as the central processing unit responsible for carrying out the jamming and detection processes. To avoid conflict with other activities, the concept of non-blocking clocks is used in the design and hardware timer with reference to the millis() function. All components are successfully initialized and reliable serial contact is maintained for debugging purposes, according to the results. By making use of the millis() method, the timing system was able to guarantee periodic monitoring and actions without interfering with the main program flow. With a detecting accuracy of 98%, the RF detectors reliably identified unlawful RF signals with very few false positives. Protecting the honesty of the testing setting, the RF jammer successfully halted illegal transmissions within a 10-m radius.
