Perancangan Alat Dispenser Otomatis Menggunakan Sistem Vending Machine RFID Berbasis Arduino Uno

Abstract

In modern times, technological advances are growing rapidly, especially in dispensers. Currently, many people are turning to the use of dispensers as a place to store drinking water, because it is more efficient in hygiene and health. People really need drinking water which pushes them in every place such as school canteens, company canteens and other places where there are dispensers. This triggered a new idea that could become a business opportunity, namely an Automatic Dispenser Using an Arduino- Based RFID Vending Machine. The working principle of this tool is to activate the output device in the form of a water pump so that water can flow after validating the RFID card. The RFID card will be used as a payment medium for drinking water, namely where the payment system uses non-cash transactions that can encourage the termination of the Covid 19 chain. In this tool there will be two choices, namely coffee and sweet tea and the price has been determined for each. Coffee is priced at Rp. 3000 and sweet tea to Rp. 2000. In addition, the amount of water released has been determined in the glass, which is 235 ml/price.
