Desain dan Implementasi Mesin Minuman Cepat Saji Menggunakan Koin Berbasis Internat of Things (Iot)

Abstract

This study aims to design and implement fast food drink machines that use coin based payment systems and Internet of Things (IoT) technology. This machine is designed to facilitate the process of purchasing drinks such as coffee and tea automatically. In this system, users only need to insert coins according to the specified price, then select the type of drink they want via a touch screen interface. This system is equipped with a coin acceptor that can verify and distinguish the type of coin inserted, as well as an ESP8266 module for Wi-Fi connectivity that allows real-time monitoring of machine status, including drink stock and number of transactions. The drink-making process begins after payment is verified, where water is heated using a heater and channeled into the cup with the help of a water pump. The results of this study indicate that IoT-based fast food drink machines can increase efficiency in serving drinks, reduce dependence on human operators, and provide convenience for users in getting drinks without having to queue. This research is expected to contribute to the development of vending machine technology in Indonesia.
