Pizza order management with real-time communication.

Abstract

This work presents the development and validation of an integrated order management system for pizzerias, using C# software and Arduino hardware, with the goal of optimizing real-time communication between customer service and the production area. The proposal aims to overcome common operational challenges in the sector, such as communication failures and manual record-keeping, through an accessible technological solution. A relational database was modeled and implemented in MySQL, following normalization principles. A C# interface was developed for order registration and management, menu management, and user management. In the production area, a module based on an Arduino UNO R3 with an RFID reader and LCD display was implemented to display orders. Validation was conducted in a controlled environment, simulating a pizzeria, with the participation of users with the profiles of server, pizza maker, and manager. The results demonstrated that the integrated system was successful. Operational tests revealed a 65% reduction in order registration time and the elimination of communication errors. Data transmission to the Arduino occurred on average in 2.3 seconds. User validation indicated high satisfaction, highlighting the usability of the C# interface and the practicality of RFID activation in the kitchen. The main limitation identified was the dependence on physical serial communication. The main conclusion is that the proposed integration between software, database, and hardware constitutes an effective and low-cost solution for automating the order flow in pizzerias, promoting significant gains in efficiency and reliability.
