These instructional approaches put students at risk, subject them to mistakes, and waste their time. The research included 30 respondents and used the Design-Based Research (DBR) framework in four stages. Phase 1 identified critical issues among students regarding safety risks and their impact on learning. These were directly connected to manual involvement in the etching processes, which were both time-intensive and potentially hazardous. Phase 2 involved developing the PCB etching machine with Arduino control, featuring an Arduino Uno, automated timing, a peristaltic pump, an agitation mechanism, LCD monitoring, and LED safety indicators. The design involved expert input, which guaranteed that the system had an enclosed structure, straightforward instructions on how it should be used, and that it was acceptable in classes. Phase 3 included a repeatable test of the prototype, during which participants provided feedback. The outcomes were categorized as "Satisfied," with gains in accuracy, reduced chemical exposure, and reduced operating costs. Phase 4 identified major design principles, including safety, automation, user-friendly instructions, and the incorporation of practical learning into the learning process. The overall conclusion of the study was that the Arduino-controlled PCB etching machine made the work much better in terms of safety and efficiency as well as the overall learning experience. It turned out to be a useful educational resource that helped to integrate theory and practice and provided a more sustainable and safer version of the traditional PCB etching techniques.
