Designing an arcade machine for easy troubleshooting requires careful consideration of several key factors. First, modular components are essential, allowing technicians to quickly replace or repair faulty parts without disassembling the entire system. Second, built-in diagnostic tools, such as LED indicators or software-based error logs, can pinpoint issues efficiently. Third, a user-friendly interface with clear error messages helps operators identify and resolve problems without specialized knowledge. Additionally, accessible wiring and labeled connections simplify maintenance. Finally, durable materials and standardized parts reduce wear and tear, minimizing the need for frequent repairs. By focusing on these elements, designers can create arcade machines that are both reliable and easy to maintain.
